摘要
分析了几种国外的复合“全工况”试验装置的工作原理和优缺点,根据国际大电网会议(CIGRE)关于高压串联阀电流强度技术导则和IEC关于静止无功补偿器(SVC)阀及高压直流(HVDC)阀的试验标准,提出了一种新型通用复合“全工况”试验装置的主电路方案。通过改进高压谐振回路,完善了SVC、可控串补(TCSC)双向阀的运行试验电路;将大电流源改为交直流两套电源系统,将高电压回路参数的电压提高至75kV,该主电路方案适用于±600kV级HVDC单向阀组件和SVC、TCSC双向阀的运行试验。
On the basis of analyzing the working principle, advantages and defects of several foreign synthetic test equipments, and according to the technical guidance on current intensity of high voltage series valve distributed by CIGRE and the test standards on the valves for SVC and HVDC distributed by IEC, a main current scheme of a new type of versatile synthetic test equipment is proposed. Through the improvement of high voltage resonance circuit, the operational test circuit for the bi-directional valves for SVC and HVDC is improved; the voltage of HV circuit is risen to 75kV by means of replacing the large current source by AC and DC power-supply system. The proposed main circuit is suitable to the operational tests of one-way valve component in HVDC and the bi-directional valves at SVC and TCSC at voltage level of ±600kV.
