This work is devoted to the development of an automated transfer switch (ATS) for the 6/0.4 kV substation. The work is relevant due to the introduction of automation and the replacement of electromechanical equipment with microprocessor devices in the power systems. At the lower (field) level, automation is driven by the use of programmable logic controllers (PLCs) and various smart sensors. The possibility of using modular PLC in automation systems is considered. Developed are an algorithm and a program for the implementation of automated regulation of the application of automatic transfer switches at a substation using the recommendations of the IEC 61131.3 “Programming languages of programmable logic controllers” standard.

Logic Controllers

The popularity of domain-specific programming languages has implications on how we test software in these domain industries. For example for programmable logic controllers five standard languages were defined and used in practice. Detailed data on popularity of these languages should show some implications on what languages to target when testing. We suggest that massive new data sources resulting from programmers may offer a new perspective on how we test domain-specific languages. By analyzing Google query volumes for search terms related to programmable logic controllers languages, we find patterns that may be interpreted as signs of actual usage in practice. Comparing with the current test generation approaches proposed by researchers our results illustrate both potentials and threats on what is needed in reality when testing programmable logic controllers.

It is noted that the effective application of programmable logic controllers in automated control systems in launching complexes is closely linked to the training of specialists, capable to carry out the development of application software. In connection with complexity of debugging of the developed programs on real process equipment an analysis of the possible variants of simulation of control processes is performed and effectiveness of virtualization of control objects on computers is noted. The developed applications of Real Games-company to create virtual control objects using 3D-graphics for training to usage of programmable logic controllers in industrial control systems are considered. The perspectives for the application software of Real Games-company in the training of specialists for automation systems of technological equipment in launching complexes are evaluated.
