　　分析了有环网运行的福建南山变35 kV电网的结构、设备状况，概括了整定计算的运行方式、主要原则。在对本电网整定过程中遇到的“整定顺序、边界限额、时间级差、相继动作、电流Ⅱ段时间、电流Ⅲ段值”等问题，分析了存在的原因，提出有效的应对措施和解决方法。论证了该片电网继电保护整定方案的合理性和可行性。
　　분석료유배망운행적복건남산변35 kV전망적결구、설비상황，개괄료정정계산적운행방식、주요원칙。재대본전망정정과정중우도적“정정순서、변계한액、시간급차、상계동작、전류Ⅱ단시간、전류Ⅲ단치”등문제，분석료존재적원인，제출유효적응대조시화해결방법。론증료해편전망계전보호정정방안적합이성화가행성。
The construction, state of equipment, operation and setting principle of the 35kV Closed-loop Running power system were introduced.The cause and solutions of such as the sequence of coordination, setting limit, differential time limit, sequential tripping, time of Ⅱstages current and current setting of Ⅲ stages were analysed. Through effective analyse and explain, the solutions of relay protection of the 35kV Closed-loop Running power system was rational and practicable.
