茂名热电厂110kV和35kV高压配电系统的改造

Modification of 110 kV and 35 kV power distribution systems in Maoming Cogeneration Power Plant

为满足地方负荷的需要 ,早期的发电厂高压配电系统普遍采用多级接线方式。通过分析茂名热电厂 110kV ,35kV高压配电系统存在的问题 ,提出了优化接线方式的改造方案 :取消 35kV母线系统 ,扩建 110kV母线系统。改造后 ,母线系统接线清晰 ,电能损耗大大降低 ,维护工作量明显减少。该改造方法对同类型的早期高压配电网络的改造具有参考价值。

In view of the problems of irrational wiring and heavy power losses in the original 110 kV and 35 kV power distribution systems of Maoming Cogeneration Power Plant, a scheme for modification was presented. The 35 kV bus system was canceled, the 110 kV bus system extended, and appropriate HV power distribution apparatus selected. The modifying method optimizes the wiring of the bus system, greatly reduces power losses and lessens maintenance;therefore, it is of referential value to transformation of early HV power distribution network of the same kind.
