摘要
分析了有多条并列运行双回线存在的福建顺昌县电网的结构、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、末端变定值、开关拒动"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 SHUNCHANG power system is introduced,which contains various lines with apposable operation. The cause and solutions of such as the sequence of coordination,setting limit, differential time limit, setting of terminal transformer station and reject tripping of switch are analysed. Through effective analysis and explaination, the solutions of relay protection of Shunchang power system are rational and practicable.
