火力发电厂电气运行危险点分析与控制措施

Analysis and Control Measures of Thermal Power Plant

火力发电厂是为人们生产、生活提供电能的重要企业。火力发电厂发电的本质是将煤炭、天然气等原材料的化学能转变为流体等介质的机械能,利用切割磁感线的原理通过汽轮机等设备进而转化为电能。火力发电厂中的电气设备是发电厂系统的重要组成部分,其中包含有为生产中机械设备和电气设备提供电力的厂用电系统和经汽轮机产生的可上传至电网的上网电力系统。因此在火力发电厂中,电气系统是否能够安全稳定运行直接影响发电厂的运行安全。火力发电厂是常规类型发电厂,系统复杂庞大,且有高温高压环境。因此,主要对火力发电厂典型电气运行中存在的危险点进行了概述,通过分析总结出火力发电厂危险点控制的重要性,并提出了有效控制危险点的措施。

Thermal power plant is an important enterprise to provide electricity for people's production and life.The essence of thermal power plant power generation is to transform the chemical energy of coal,natural gas and other raw materials into the mechanical energy of fluid and other media,and use the principle of cutting magnetic sensor wire to transform it into electric energy through steam turbines and other equipment.Electrical equipment in the thermal power plant is an important part of the power plant system,which includes the power supply system for the mechanical equipment and electrical equipment in the production,and the power system generated by the steam turbine that can be uploaded to the power grid.Therefore,in the thermal power plant,whether the electrical system can operate safely and stably directly affects the operation safety of the power plant.Thermal power plant is a conventional type of power plant,and the system is complex and huge,and has a high temperature and high pressure environment,in the previous operation experience,we have found and summarized many dangerous points.This paper summarizes the dangerous points existing in the typical electrical operation of thermal power plant,summarizes the importance of the dangerous point control of thermal power plant,and puts forward the measures to effectively control the dangerous points.
