350MW 汽轮发电机组保安电源调试实践

摘要

Diesel generator sets are important parts of AC emergency power supply system for large generator unit.When a prolonged power outage happens in auxiliary power source for power plant due to power grid faults or other reasons, diesel generators provide necessary AC power, such as turbine turning motor power, sealing oil pump, jacking oil pump power, and AC lube oil pump power, to avoid damage in the shut-down of the turbine generator sets.In this paper, the AC emer-gency power supply system test process of a new power plant has been studied.After test using the discussed process, the design of the AC Emergency Power Supply System has been proved to meet the design and production requirements.%柴油发电机组作为现在大型单元机组交流事故保安电源系统的重要组成部分，对由于电网或其他原因导致的发电厂厂用电源长时间停电时，可以给发电机组提供安全停机所必须的交流电源，如汽轮机盘车电机电源、密封油泵电源、顶轴油泵电源、交流润滑油泵电源等，从而保证了汽轮发电机组在停机过程中不受损坏。本文针对某新建电厂的交流事故保安电源系统的调试进行了研究，该机组在经过本文所写的调试后，交流事故保安电源系统完全满足设计要求，达到了机组投产的要求。
