Abstract

The invention discloses a chained STATCOM (static compensator) control system based on a serial communication manner, and the system comprises a master control case, a functional case, a phase control case and a unit controller, wherein the master control case and the functional case are used for performing control, monitoring and protection on the chained STATCOM; the phase control case is used for performing control, monitoring and protection on three phases of the chained STATCOM; the unit controller is used for performing control, monitoring and protection on a chain link unit of the chained STATCOM; and the serial communication manner is adopted among the master control case, the functional case and the phase control case.

Description

technical field [0001] The invention relates to the technical field of flexible AC power transmission and distribution, in particular to a chained STATCOM control system based on a serial communication mode. Background technique [0002] With the rapid development of the power industry, the use of power electronics technology to adjust and control the main parameters of the power system to improve the controllability, effectiveness and reliability of the power system is the "AC flexible transmission system", that is, the flexible AC transmission system. (Flexible AC Transmission Systems, FACTS) technology has been widely concerned, researched and applied. [0003] Static Synchronous Compensator (STATCOM) based on voltage source inverter is a brand-new FACTS technology based on fully controlled devices. Compared with the traditional thyristor-controlled static var compensation device SVC, it has the following advantages: The adjustment speed of STATCOM is faster and the oper...
