Simulation of the static synchronous compensator for the electrical system with non-linear load

Abstract

This paper presents the STATCOM model in PSIM, which compensate reactive power and current harmonics from the non-linear load. Reactive power consumption and harmonics current of non-linear load given from measurement. The model of STATCOM is a multi-level voltage inverter. Constant system voltage, power factor and harmonics currents are controlled. All modes are realized and plots are plotted.

PLC control method for speed regulation of automatic frequency converter of high-voltage electrical equipment

“…In formula (4), 2 ( ) e t represents control deviation, dt represents the dynamic control index. In the actual PLC control process, it may be affected by the control communication level, and there is a certain control deviation.…”

“…PLC is a new type of controller, which can realize automatic control [1][2][3] through logic programming. At the same time, it has many different control production functions such as calculation, timing, etc., which is of great significance to improve the production efficiency of enterprises.…”
