Abstract

The invention discloses a triggering device and a triggering control method for a thyristor valve block of a high-voltage TSC (thyristor switched capacitor), and belongs to the field of electric system controllers. With the triggering device and the triggering control method, the problems of complex structures of existing triggering devices and complexity of existing triggering control methods are solved. A control unit is connected with the triggering device. The triggering control method includes that an external clock circuit is adopted to provide clock signals to a logical processing unit, collected SIN signals are judged to acquire switching time, switching signals are outputted according to the switching time, and the switching signals are converted to optical signals through a light transmission circuit to be outputted to a light receiving circuit after being amplified by a driving circuit; and the light receiving circuit outputs electric pulse signals to an optical-coupling isolation circuit II, and input sides of two optical-coupling isolation circuits are switched on simultaneously when the electric pulse signals are of low levels, so that two triggering signals are outputted by two triggering units to gate poles of the thyristor valve block of the high-voltage TSC simultaneously. The triggering device and the triggering control method are applicable to electric systems and industrial systems.

Description

technical field

[0001] The invention belongs to the field of power system controllers, and in particular relates to a trigger device and a trigger control method for a thyristor valve group of a high-voltage TSC. Background technique

[0002] At present, my country's power line loss structure is 220kY, 110kV, 35kV and 10kV. According to the analysis of relevant data, the reactive power load of the power system at this stage is about 1.3 times the active power, and the value continues to increase. If the reactive power cannot be compensated locally, the reactive power required by the user load will be provided by the long-distance power generation and distribution equipment, which will make the power distribution, transmission and power generation facilities unable to fully play their roles, and reduce the power generation and transmission costs. Ability to deteriorate the power supply quality of the power grid, and may cause the system voltage to collapse in severe cases, ca...
