摘　　要：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。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 Ⅱ stages 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.
