摘要
从蓄能机组的工况特征和接线方式入手,对抽水蓄能机组同期装置的主要特点,尤其是不同工况下的相序特征进行分析,揭示了蓄能机组和常规机组同期的本质区别。指出了当前抽水蓄能机组同期装置及回路设计中存在的风险和缺陷,并提出了改进建议和方案。
Starting from working condition characteristics and connection mode of pump storage group,this paper analyzes main characteristics of synchronizing device of pump storage group especially features of phase sequence under different working conditions.It indicates essential differences of pump storage group and conventional group and points out risks and defects existing in synchronizing device and circuit design.In addition,it proposes improvement suggestions and schemes.
