Abstract

The invention relates to a digital-analog hybrid simulation system and a digital-analog hybrid simulation method of a controllable series compensator. The system is used for training technical skills and comprises a low-voltage physical model, a low-voltage physical model control system and a digital simulation machine, wherein the low-voltage physical model control system controls the low-voltage physical model during independent running, and the digital simulation machine controls when digital and analog mixed simulation is performed; the low-voltage physical model control system can control a TCSC (Thyristor Controlled Series Compensation) digital simulation module main circuit in the digital simulation machine. The system and the method can perform local / remote operation as well as real-time online simulation study on the low-voltage physical model, are flexible and variable in teaching model, and can achieve a good demonstration teaching effect.

Description

technical field [0001] The invention relates to a simulation system and a simulation method in the field of power electronics, in particular to a digital-analog hybrid simulation system and a simulation method of a controllable series compensator. Background technique [0002] Power electronics technology is a technology that uses power electronic devices to transform and control electric energy. Power electronics technology and devices are widely used in flexible AC transmission, high-voltage DC transmission, AC-DC power transmission and other fields. TCSC is an important branch of flexible AC transmission system, which uses the smooth control of controllable series compensation impedance to improve the transmission capacity and stability of the power system. The TCSC used in engineering is a controllable series capacitor. It connects the capacitor in series in the transmission line, and at the same time connects a thyristor valve-controlled reactor in parallel at both end...
