电厂保安电源接线改造设计及保安负荷分类原则

针对老电厂改扩建过程保安段电源因运行方式变化,需新装设柴油发电机作为保安母线的备用电源的情况进行了分析,在对原设备不做大的改动的前提下,设计了一种简单的接线方式,并对保安负荷提出了创新性的分类原则,实现了投资少,工期短,改动小的目的,为同类型电厂保安段电源改造和柴油发电机组选型提供了依据.

Reconstruction Design of Emergency Power Supply Circuit Wiring Diagram and Principle of Security Load Classification

On account of operation mode changes from old power plant reformation and expansion construction,the installation of new diesel generators was required for safety emergency power supply,on the premise of making small changes to the original equipments,a simple wiring mode was designed,and innovative classification principle of existing security load was put forward.Thus realized the purpose of less investment,short construction period,small changes,provided evidence for reconstruction design of emergency power supply and selection of diesel generator in the same type of power plant.
