摘要
针对接地变压器及相关设备的继电保护回路改造问题,阐述了新能源场站汇集系统接地变压器综合保护测控装置出口跳闸回路不能满足相关标准的要求,提出了两个保护回路改造方案,同时进行了两个改造方案的比较。结果表明,方案2在提高继电保护装置性能、改造资金、工作量方面优于方案1。
In response to the renovation of relay protection circuits for grounding transformers and related equipment,it is explained that the tripping circuit at the outlet of the grounding transformer comprehensive protection device in the new energy station collection system cannot meet the requirements of relevant standards.The article proposes two protection circuit renovation schemes and compares them.The results show that the second scheme is superior to the first scheme in terms of improving the performance,renovation funds,and workload of the relay protection device.
