摘要
针对超高压直流输变电系统用的直流开关转换设备的检验检测如何在试验室实施,笔者通过对直流输电系统的运行工况及特性进行研究,依据电网参数及工况的要求定性试验方法或方式。通过对转换电流开断能力试验的相关分析及PSCAD仿真试验模拟,设计了两种试验回路以满足试验参数的要求,文中介绍其中之一合成试验回路的设计及分析,并进行计算,对其实施进行了必要的阐述和探讨。
For testing the high voltage in laboratory, the working conditions direct current (HVDC) circuit breakers of and characteristics of HVDC distribution HVDC distribution system system are analyzed, and two test circuits for the HVDC circuit breakers are designed according to the grid parameters and working condition requirements, as well as PSCAD simulations. The design of one of the test circuits, named direct test circuit, is described in detail and calculated.
