摘要
针对地下分布式蓄放冷热电联供能源中心厂用电率高、不需要第3路电源或事故保安电源、电气设备布置空间有限、不宜采用油浸变压器的特点,分析了3种厂用电方案,提出了双分段开关母联支接备用厂用电接线优化设计,并分析了其接线可靠性及投资经济性。
The underground distributed CCHP energy center with cool and heat storage is characterized by high rate of auxiliary power,no need of the third power or emergency power supply, the limited space for the electrical equipments, and iuadaptability of oil-immersed transformer. Thereupon, this paper presents three schemes for auxiliary power supply, presents the optimizing design of standby auxiliary power wiring with two-step switch and bus-connected subcircuit, and finally analyzes its wiring reliability and investment economy.
