Russian Smart Contactless Reversing Starters for Automatic Process Control Systems of Medium Thermal Power Plants |
P.M. Gofman, V.V. Kolesnik, I.V. Kovalev, K.K. Pershakova
The article considers the applicability of Russian non-contact reversing starters in subsystems of distance control of automatic process control system actuators for medium thermal power plants. The authors analyze the market of domestic developers and manufacturers of smart contactless reversing starters. The article only includes the analysis of microprocessor-based devices and does not consider semiconductor-based starters (such series of starters as PBR-3A, BiSTART and others). The article provides a comparative analysis of the technical characteristics of Russian smart contactless reversing starters. The flexibility of control circuits of check and control valves can be increased by introducing smart contactless reversing starters in various automatic process control systems of thermal power plants, including the subsystems of technological protection and safety interlocks. The authors consider the compliance with regulatory documents guiding the construction and composition of such systems. The article will be useful for designers of automatic process control systems of medium thermal power plants, operating personnel, as well as domestic developers of smart contactless reversing starters. The authors do not consider the applicability of smart contactless reversing starters in control circuits of check and control valves of large thermal electric power plants, while a part of electric check valves at such power plants is equipped with electric motors with better capacities than those of contactless reversing starters. For this type of valves, electromechanical starters of the fourth (fi fth) value are applied, though they are not analyzed in this article.
Keywords: intelligent contactless reversing starters; programmable logic controller; a communication device with the object; actuator; thermal power plant; high speed interface; shut-off and control valves; the subsystem of technological protection and protective interlocks; motor.
