Voltage reactive power integrated control device based on magnetic control reactor

Abstract

The voltage reactive synthesis control device based on magnetic control reactor in power system field comprises: connecting a trigger control module to the three-phase six-column epoxy resincast dry reactor, an impulse electric-to-optical transformation circuit between said trigger control module and intelligent control module, a capacitor switch module to breaker coil on an extra capacitor, and a reactor protection module to breaker coil on an extra magnetic control reactor; when detecting abnormal of the said dry reactor, automatic cutting off the reactor, and connecting the main on-load tap switch control module, capacitor switch module and reactor protection module to intelligent control module. This invention realizes intelligent control for power voltage stabilization and reactive power dynamic balance on precondition of high reliability.

Description

Technical field [0001] The invention relates to a device in the technical field of power systems, in particular to a voltage and reactive power comprehensive control device based on a magnetron reactor. Background technique [0002] At present, the reactive power compensation in the power system substation is generally the circuit breaker switching capacitor bank. With the gradual increase of power system cable lines, when the load is light, these capacitive reactive power appears to be excessive. It is difficult for traditional SVCs to compensate for these capacitive reactive power, resulting in high system voltage and unbalanced reactive power, which affects system stability. And the safety of electrical equipment is not conducive to the stable and efficient operation of the power system. Thyristor phase control (TCR) uses thyristor to control the reactor to compensate reactive power. The control process is executed quickly, and the range of reactive power compensation can be e...
