Novel reactive power compensator control device and control method thereof

Abstract

The invention discloses a novel reactive power compensator control device, which comprises an ADDC (automatic data direction control) controller, an electric receiving current sampling module, a bus voltage sampling module, a TCR (thyristor controlled reactor) current sampling module, a synchronous detection module, a band-pass filter module, a six-phase pulse output module and a TCR, wherein the analog signals sampled by the electric receiving current sampling module, the bus voltage sampling module and the TCR current sampling module are filtered by the filter module and are sent to the ADDC controller; the synchronous signal detected by the synchronous detecting module is also sent to the ADDC controller; the pulse angle is calculated by the ADDC controller, the triggering pulse information is sent to the TCR in a pulse way at zero-crossing time by the six-phase pulse output module, and the TCR sends out current according to the pulse to perform reactive power compensation. The device provided by the invention can be used for performing reactive power compensation fast and efficiently.

Description

technical field [0001] The invention relates to a Siemens SIMATIC TDC control platform and related modules, in particular to a novel reactive power compensator control device and a control method thereof. Background technique [0002] With a large number of non-linear loads such as modern power electronic equipment connected to the power grid, the power supply quality of the power grid is seriously affected. Among them, the large number of applications of various power electronic switching devices and frequent fluctuations in loads are the main sources of interference, resulting in a series of bad Affected, electrical equipment cannot work normally. Static dynamic reactive power compensation SVC device is used to suppress harmonics and compensate reactive power, but its reactive power compensator control device has disadvantages such as long response time, poor detection accuracy of grid signal acquisition, low calculation accuracy, and poor working stability of the device. ...
