PCS design. Development of projects for transformer substations of various types - tp, ktp, bktp and ktp-v, ktpn Made of polymeric materials

Design and development of automated process control systems is a process focused on increasing the productivity of industrial enterprises and the quality of manufactured products. Moreover, an automated process control system makes it possible to provide a fundamentally new quality of production process administration, which is especially important for any modern enterprise. In particular, automated process control systems are necessary when the technological processes used in the organization are complex and inadmissible failures that can lead to significant material losses.

Competent design of automated process control systems minimizes the likelihood of the human factor affecting the work and, as a result, the quality of products.

The company "Arman" has the necessary engineering resources to provide services in the field of design of process control systems:

Design of process control systems. Development of automated process control systems.
Supply of equipment for control systems (APCS).

As a result of the APCS design, the customer receives a ready-made APCS infrastructure for his facility.

The result of the APCS design is a completely ready-made APCS infrastructure, which is maximally adapted to the customer's facility. Modern methods of designing industrial control systems are based on strict compliance with standardization requirements regarding:

Reliability

uninterrupted;

· functionality;

Convenience and ease of use.

The most important quality - reliability - during the design of process control systems is achieved through the use of internal diagnostic subsystems, as well as through the introduction of monitoring and standardization systems. On the other hand, competent design is not always enough to build an effective APCS infrastructure. To achieve optimal results in the implementation of such large-scale projects, it is necessary to use high-quality modern equipment from reliable, time-tested manufacturers.

After the completion of the design processes, the installation and commissioning of the systems follows. At all stages, from design to commissioning, the issues of quality and technical compliance of systems with modern requirements are important, which are guaranteed by the specialists of the Arman Engineering Center.

Purpose and objectives of designing automated control systems

The purpose of designing an automated control system at an industrial enterprise is to create a project for a local or automated control system for technological processes of an object or a combination of such objects.

The main tasks to be solved in the process of designing an automated control system include the following tasks.

· Analysis of the automation object and formulation of technical requirements for the system.

· Determination of a rational level of automation, determination of the structure of the control and management system of the automated process.

· Choice and substantiation of methods of control, regulation and management of technological processes, forecasting and diagnosing.

· Choice of a complex of technical means of automation.

· Optimal placement of automation equipment on process equipment, on site, on boards and consoles in control stations.

· Ensuring the effectiveness of methods of installation of technical means of automated control systems and communication lines.

· Preparation of technological and operational documentation.

· Ensuring the openness of the automated control system.

The requirements for the process of designing and introducing into production automated control systems for industrial facilities, as a specific class of technical systems, are influenced by the following features of these systems:

physical heterogeneity of both control objects and devices and elements included in automated control systems;

· a continuous dynamic process of functioning of both control objects and automated control systems;

· multi-criteria conditions of functioning and performance, while many criteria are contradictory, for example, stability and accuracy, reliability and weight and size characteristics, etc.;

· Uncertainty of the set parameters and disturbing influences, determined by the presence of not only external, but also internal influences, non-stationarity in time of the parameters of devices and elements of control systems;

The presence of several control loops, the multidimensionality of control systems.

An effective solution of the problems facing the Engineering Center arising in the design process is impossible without forecasting and modeling of automated and designed objects, development of advanced design tools and methods, analysis of forecasts for the development of automated technological processes and technical means of automation. These tasks can be solved by using unified design solutions, improving the regulatory framework for design and the system of estimated indicators of the quality of design solutions, improving the organization and management of the design process.

One of the determining factors for improving the quality and efficiency of projects of automated control systems in the context of improving the design process and the widespread use of design automation systems is the development of regulatory support. Regulatory and technical documents that are part of the regulatory support for the process of designing automation systems are a set of norms, rules, requirements that are mandatory for implementation, developed in the prescribed manner and approved by the relevant authorities. These documents include documents of the state standardization system (GOST, OST, STP) and documents containing, along with mandatory requirements, advisory ones that allow possible solutions depending on specific conditions and related factors (SNiP, RD, MU). Such documents are widely used in the process of designing automated control systems.

APCS design stages

At all stages and stages of designing an automated process control system, designers must be guided by the state standards of the Unified System of Standards for Automated Control Systems (ESS ACS). The ECC ACS system is a complex of interrelated GOSTs that establish terms and definitions, types and composition, rules and methods for development, acceptance and operation, requirements for the ACS as a whole and its components, and requirements for technical documentation.

The standards establish the following four stages in the development of APCS projects:

· Feasibility study (feasibility study).

· Terms of Reference (TOR).

· Technical project (TP).

· Working documentation (RD).

Instead of the stages of TP and RD, it is allowed to develop an automated process control system in one stage "Technological design" (TRP). The TRP stage is performed in cases where standard APCS designs are used or when economical individual projects are reused.

6. Stages of development, implementation and reliability of process control systems.

Some enterprises in their economic management have transformer substations (TS). They are consulted by Gefest company. Such companies suffer large losses due to reactive as well as active losses of TP. Measurements, laboratory tests, and their maintenance also require investments. The owners of the companies do not see visible profit and consider these investments as expenses. This is due to the fact that there is a constant expenditure of money, but nothing is produced. However, the presence of its own transformer substation means high-quality electricity, as well as the uninterrupted operation of its generation. To make a profit, it is necessary to calculate the balance of economic and production costs. This is possible with the help of TP design.

TP design flaws

The design of TP, as well as the design of electricians, is carried out according to the developed schemes. When designing a transformer substation, a technical task is developed for the designer, then a diagram of the transformer substation and switchgear is developed, the required power of the transformer, protection, grounding, short circuit currents is calculated. After calculations, the necessary equipment is selected (insulators, transformers, tires, etc.). Then, the draft TP is coordinated with the authorized bodies. The final stage is the transfer of the project to the customer, after which the electrical installation begins. We must not forget about the analysis of the work done: tests, conclusion of contracts, start of use.

Consider an example of designing a transformer substation in Moscow

The Gefest company was entrusted with a project for the design of TP at a bakery. The enterprise was already working, it was necessary to reconstruct the transformer station built there in order to reduce the cost of its maintenance and increase efficiency. The bakery has two oil transformers, one of which is a backup, and the second is used only by 60%. The enterprise works to the maximum only 8 hours a day due to the technological features of production: bread is baked for 8 hours, the rest of the time is spent on preparation (dough is prepared, dough is kneaded). The plant also produces pasta (the equipment in this workshop consumes quite a bit of energy).

The company Gefest carried out calculations of the energy consumption of the bakery. It was revealed that the enterprise paid the supplier for the electricity of both transformers, as well as reactive consumption. TPs were not equipped with metering devices, so all calculations were carried out according to established standards, naturally, in favor of the supplier. Although the transformers were not used to their full capacity, the plant paid for the full cost of use. In the course of the design solution of the problem, the TM-600 was replaced by a TM-400 of lower power, the RU-10 circuit was reconstructed, namely, the spare transformer was turned off, but if necessary, it could be turned on instantly. The TM was equipped with a condenser unit that operates automatically, which reduced the cost of generation and power flows.

a month was developed, a week was agreed upon, and two weeks were required for reconstruction and laboratory tests. This is a rather costly process. Initially, Hephaestus made a calculation of economic efficiency and payback period (28 months). This implies the conclusion that the design of TP is an important stage that helps to save.

It is also necessary to assess the possibility of providing backup power, the correspondence of the power of transformers and the load on them, the need to install compensating devices, consumption modes, the need to install metering devices.

The transition to the use of advanced technology is an innovative stage in the development of Russian industrial production, which seeks to achieve the highest possible performance of both used and newly designed equipment. This is done in order to minimize any loss of production performance. The use of automated process control systems (APCS) is the only condition for the existence of high quality management and control of industrial facilities.

APCS- this is a single system solution that will provide you with the automation of the main tasks and processes in production and its individual sections. The very concept of “automated” explains the need for the participation of the human factor in individual operations in order to additionally maintain control over the process.

The design of process control systems is a focused process of increasing the productivity of all industrial enterprises, the quality of manufactured products and safety at the facility. Also, the automated process control system additionally provides the latest quality of production process administration. This is always true for any modern enterprise. The need for automated process control systems appears when technological processes are characterized by increased complexity and inadmissibility of failures that will lead to significant material losses. Exceptionally competent design of automated process control systems significantly reduces the likelihood of extraneous human factor impact on the entire operation of the enterprise. One of the main and mandatory functions is archiving. After all, it is very important to be able to analyze the operation of systems for global analysis in slow, long processes.

The APCS structure, which operates as a single operator control system, includes:

one or more control panels;
special means of collecting, transporting, processing and archiving information about the course of the production process;
typical equipment: controllers, sensors and other automation tools;
industrial networks used for information communication of subsystems;

The APCS diagnostic system monitors the condition of all components in production, thereby increasing the quality and service life of mechanisms and machines. In turn, the development and implementation of APCS systems are interrelated processes, including the design of APCS, software, dispatching, and controller programming.

The design of automated process control systems of any degree of complexity is necessary for creation of a ready-made infrastructure for an automated process control system in production. Specialists of OOO "Neftegazinzhiniring" design automated process control systems for both newly built facilities and already operated enterprises. In the latter case, the goal of creating a new automated system is to change the technological process, increase the productivity of processes, improve the quality of products or services provided, reduce operating costs and other benefits as a result of the most optimal control of technological processes.

Effective administration of technological processes includes not only management functions, but also informational properties, measurement of system operation parameters, collection, storage and analysis of information and then formation of the system operation algorithm.

In order for the entire automated control system to work efficiently, smoothly and reliably and was maximally adapted to the requirements at the facility, it is necessary to design the automated process control system to create the most optimal and rational level of process automation.

APCS design stages

The main stages of work on the design of APCS systems are:

pre-project stage
draft design development
development of a technical project
development of working documentation (for installation work)
coordination of the project with the customer
obtaining a state expert opinion

On the pre-project preparation technical audit, examination and analysis of the specifics of the object are carried out, as a result of which preliminary design solutions are developed. If the Customer already has a technical task, our specialists make an estimate for the design of the process control system. Based on the results of agreeing on the estimate and upon signing a contract for the provision of services, APCS design engineers begin to develop an APCS project.

AT APCS project(in the technical and working documentation) a system concept is developed that allows the most successful implementation of the entire APCS project as a whole. The project provides basic information about the developed system of automated process control. For example, the project provides a set of technical automation equipment (instruments, software, etc.), their hierarchy, drawings, and a structural and functional diagram of optimal placement. Engineers-designers of LLC "NGI" are working out a ready-made working scheme for automation and dispatching of production processes at the facility.

All design stages are carried out in accordance with state standards, namely:

GOST 34.601-90 "Automated systems. Stages of creation"
GOST 34.201-89 "Types, completeness and designation of documents when creating automated systems"
Government Decree No. 87 of "On the composition of sections of project documentation and requirements for their content"
