摘　　要：[目的]为了降低燃机电厂初期投资,在保证机组安全的同时,通过黑启动功能获取广东辅助服务经济补贴,提出了扩建燃机时采用多台柴油发电机组的配置方案,用于9F机组事故停机保安电源,同时又作为原9E机组黑启动电源。[方法]为了实现技术经济最优化,通过柴油发电机组配置及厂用电接线的多方案比选论证,给出了合理配置方案。并对推荐方案的事故停机控制逻辑以及黑启动控制逻辑进行论述。[结果]通过黑启动试验结果表明,各电气量均满足规范要求,推荐方案能满足黑启动功能并通过电网公司验证。[结论]多台柴油机同时用于黑启动及保安功能的方案,为今后燃机电厂黑启动及保安电源工程设计提供参考及借鉴。[Introduction] In order to reduce the initial investment in the gas turbine power plant and ensure the safety of the unit, and obtain the economic subsidy of Guangdong auxiliary services through the black start function, the configuration scheme of using multiple diesel generator units is proposed when expanding the gas turbine, which are used as both the emergency shutdown power supply of 9F unit, and the black start power supply of the original 9E unit. [Method] In order to achieve technical and economic optimization, a reasonable configuration scheme was given through multi-scheme comparison and demonstration on the configuration of diesel generator units and the auxiliary power wiring. The emergency shutdown control logic and black start control logic of the recommended scheme were also explained. [Result] The results of the black start test show that all electrical quantities meet the requirements of the specification, and the recommended scheme can meet the black start function and pass the verification of the Grid Company.[Conclusion] Multiple diesel generator units are used for both black start and emergency functions in the scheme, which provides reference for the future engineering design of black start and emergency power supply in gas turbine power plants.
