Control Systems for Semiconductor Power Regulators in Distribution Networks

An approach is presented to the construction of control systems for semiconductor power regulators for distribution networks with the aim of balancing network operating modes and reactive-power compensation. The main functions to be realized by control systems of semiconductor power regulators are formulated. A generalized structure of the control system is presented, applicable for a wide class of circuit solutions for semiconductor power regulators. A generalized algorithm for the control system operation is proposed. An example of implementation of a hardware–software complex of a control system for one of the semiconductor power-regulator circuits is presented. Results of experimental studies of the control system operation in automatic mode of a prototype of one of the semiconductor power-regulator schemes showing the balancing of active power in the network under a dynamically changing load are given.
