| 摘 要： | 贵广二回极2于2007年5月29日进行了小功率(150 MW)无通信逆变站手动紧急跳闸试验。试验方案预期，在试验工况下，在逆变站按下紧急停机(ESOF)按钮后，整流站将在1 s后由直流低电压保护(27DC)启动闭锁顺序。但实际试验结果显示，整流站由换流器过压保护59/37DC一段启动紧急停机顺序，退回至备用状态。本文对这种异常情况进行了分析，并对分析结论做了PSCAD/EMTDC仿真验证。根据分析建议的试验方案进行的再次试验证明了分析的正确性。

| Abstract: | The low load (150 MW) manual emergency switch off (ESOF) trip test at inverter station without telecommunication of Guizhou-Guangdong II HVDC project Pole 2 was carried out on May 29, 2007. It is expected by the test project that in this situation the rectifier station will be blocked by the DC undervoltage protection (27DC) after the ESOF button is initiated at the inverter station. However, it was actually tripped in the test by the converter overvoltage protection (59/37DC). Analysis on this abnormal results and the PSCAD/EMTDC simulation are addressed. A new test scheme based on this study has been implemented to verify our conclusion. |
