Description
Technical field
The utility model relates to a kind of static passive compensation device.
Background technology
Static passive compensation device (Static Var Compensator is called for short SVC) as the reactive power compensator a kind of in parallel that grows up the latter stage seventies, is widely used in smelter and the electric power system.How suppressing quick impact load causes in the smelter voltage fluctuation and flickering, improve the unbalanced operation situation of load, is a difficult problem of necessary solution in the design of SVC device.And a large amount of at present SVC devices based on Programmable Logic Controller PLC design that adopt because the PLC arithmetic speed is slower, are difficult to satisfy the requirement of complicated control algolithm and rapid response speed.
Summary of the invention
The purpose of this utility model aims to provide a kind of static passive compensation device based on the digital signal processor DSP design, to overcome the weak point of existing product.
By a kind of static passive compensation device of this purpose design, comprise main circuit part and control circuit part, main circuit comprises thyristor-controlled reactor TCR, thyristor switchable capacitor TSC and filter FC, i.e. TCR+TSC+FC type; Control circuit comprises controller, light/power conversion circuit and circuits for triggering; It is characterized in that its controller adopts digital signal processor DSP.
The controller of this static passive compensation device is owing to adopted digital signal processor DSP as control board, thereby response speed is fast, can suppress the voltage flicker that impact load causes in the smelter, plays the effect of burning voltage.It is simple in structure, easily manufactured, practical.
