油机备用电源系统的自动卸载设计

Automatic Unloading Design of Reserve Power Supply System of Diesel Generator

介绍油机备用电源系统的固有特点(装机容量的有限性、发电能力的可变性、低频及低电压保护配置),阐述油机电源系统自动卸载设计的必要性(油机系统的相对过载及其引发的频率电压下降),提出油机系统自动卸载有效设计的途径(油机系统自动卸载的一次配电设计、油机系统自动卸载的监控设计)。

The inherent characteristics（the finiteness of installed capacity,the variability of power generation capability and the protection configuration for low frequency and low voltage） of the reserve power supply system of the diesel generator are introduced,the necessity（the relative overload of the oil engine system and the reduction of frequency and voltage triggered by it） of the automatic unloading design of the power supply system of diesel generator is expounded,and the effective design approaches（the primary power distribution design and the monitoring design of the automatic unloading of the diesel generator system） for the automatic unloading of diesel generator system are put forward.
