摘要
楚雄侧孤岛运行是云广直流输电系统的正常运行方式之一。介绍了云广直流仅带小湾电厂孤岛运行方式的调试项目,包括联网-孤岛运行方式转换试验、孤岛系统稳态运行以及运行过程中模拟故障或扰动的试验。基于该孤岛运行方式的现场调试,对系统的实际运行特性进行了分析,结果初步验证了云广直流孤岛运行方式的可行性。现场试验及分析为进一步开展后续孤岛运行方式调试打下了基础,并为系统处于这种孤岛方式时的实际运行提供指导。
Islanding operation at Chuxiong side is a normal operation mode for Yunnan ？？Guangdong UHVDC transmission system.The paper describes the on-site commissioning tests of the system islanding operation as it is supplied only by Xiaowan Power Plant at Chuxiong side,including the tests of mode changing between AC/DC parallel operation and islanding operation,of steady state performance,and of dynamic performance with disturbances or faults occurred in islanding operation.Based on the testing results,the actual islanding system operation performance is analyzed,and it is proves that the system runs smoothly in the islanding operation mode.The tests and analysis provide a technical foundation for further on-site commissioning of the system islanding operation and a guidance for its actual operation as it being in such islanding operation mode.
