Current Detection Simulate for STATCOM Dynamic Compensation System

Abstract

In view of low-pressure area for dynamic reactive power compensation device application present situation, a more advanced static reactive power compensation techniques was proposed that is STATCOM (Static Synchronous Compensator-STATCOM) which based on the modern power electronic technology, and it applied to the low-voltage dynamic reactive power compensation area, developed a new and more advanced low-voltage dynamic reactive power compensation device. In this paper, STATCOM compensation system simulation model was established in MATLAB6.5, futher to study its real-time compensation. Theory analyze and simulation results indicate that compare with static capacitor compensation，dynamic compensation achieved zero phase angle between power source current and voltage on rating frequency，demand for power supply rating power is reduced and power transmission performance is ensured.
