Research on Static Var Compensator Control System Based on SIMATIC - TDC

Abstract

This paper proposes a new static var compensator control system with SIMATIC-TDC as the master controller and DSP as the auxiliary controller. Siemens TDC is a high-end controller with excellent data processing capacity, which can satisfy the current reactive compensation control algorithm to finish open loop and close loop control. Meanwhile, the programming configuration software is also fully featured, and widely applied in smelting, chemical and power industries. However, the auxiliary controller consisting of DSP and CPLD can quickly finish precise processing of signals (such as high-frequency sampling and signal frequency spectrum analysis). The static var compensation control system consisting of the master controller and the auxiliary controller has now been applied in many projects, achieving sound compensation effect.
