摘　　要：TCSC旁路的目的在于当系统发生故障时抑制短路电流、减轻氧化锌避雷器 MOV能量吸收的负担 ,使 MOV不致工作在太高的保护水平 ,从而在选择设备时 ,降低MOV的投资。因此 ,当故障发生时 ,快速有效的起动旁路模式十分重要。本文就能耗与能耗梯度两种旁路起动模式做出分析对比 ,指出它们各自的特点 。The purpose of bypassing Thyristor Controlled Series Compensation (TCSC) is to restrain the short-circuit current and lessen the burden of absorbing energy using ZnO arrester MOV when the system breaks down. It also ensures that MOV doesn't work at a higher level and reduces the investment of MOV when choosing the equipment. Therefore, it's very important to start bypass mode rapidly and effectively when fault occurs. This paper analyses the two starting mode of energy consumption and energy consumption gradient, elaborates their characteristics and verifies them using digital simulation.
