摘　　要：为检验投产后发电机组TPY级电流互感器暂态性能是否满足保护动作性能要求,以某电厂600 MW发电机组TPY级电流互感器配置为基础,通过分析TPY级电流互感器暂态性能校验判据,提出系统性暂态性能校验方案,实现校验流程规范化。结合机组不同接线方式下实例校验分析,对该方案实现过程进行具体阐述,为同类机组开展TPY级电流互感器暂态性能校验工作提供参考。In order to prove the conformity of the transient characteristics of the TPY class current transformer forgenerating unit in service with the requirements for the protection system performance,Based on the configuration of TPY class current transformer for the 600 MW generating unit in a power plant,by analyzing the verification criterion for the TPY class current transformer’s transient characteristics,a systematic verification scheme of the transient characteristics of the TPY class current transformer for 600 MW generating unit is proposed to standardize theverification process.With analysis on the practical verifications with different connections,the implementation of the scheme is given in detail to provide a reference for the verification of the TPY class current transformer’s transient characteristics in similar units.
