摘要(Abstract):
依据"由简至繁、循序渐进"的原则,设计并开展了分布式发电系统保护控制的调试工作。分别进行了110 kV变电站、分布式电源、数据中心和站用电系统等分系统的单独调试,并在此基础上,分步开展了分系统之间的集成测试。最后,通过实际切除外部市电,以验证分布式电源的黑启动功能。结果表明,在外部市电全失后,分布式发电系统可在2 min 40 s内恢复数据中心的供电和制冷,从而确保数据中心的稳定可靠运行。
This paper designs and carries out the protection and control system commissioning for the distributed power generation system based on the principle of "from simple to complex and step by step". The subsystems of the 110 kV substation, the distributed generation, the data center and the auxiliary power system are commissioned. Furthermore, the integration testing between the subsystems are carried out step by step. The outside power supply is cut off in practice for black start test. The results show that the distributed power generation system can recover power supply and the refrigeration for the data center within 2 minutes and 40 seconds, thereby insuring the stable and reliable operation for the data center.
