电厂发电机变压器保护原理及继电保护方式分析

Analysis of the Protection Principle and Relay Protection Mode of Power Plant Generator Transformer

我国市场经济在稳步、健康发展的同时,各个行业的用电需求逐步呈现出多元化特点,且用电量迅猛增加。新时期,发电厂的工作压力逐步加大。发电机与变压器是电厂安全与稳定运营的重要设备支持。电厂发电机变压器在长年累月的运行过程中,难免会出现一些性能故障。为提高电厂发电质量,并为民众提供优质的用电服务等,电厂逐步加大了发电机变压器保护力度。论文从理论角度出发,分析了电厂发电机变压器保护原理与继电保护的重要性,并提出了几点继电保护方式,以供参考。

While China's market economy is developing steadily and healthily,the electricity demand of various industries is gradually becoming diversified,and the electricity consumption is increasing rapidly.In the new period,the working pressure of power plants gradually increases.Generator and transformer are the important equipment support for the safe and stable operation of the power plant.During the perennial operation of power plant generator transformer,some performance faults will inevitably occur.In order to improve the quality of power generation and provide quality electricity services for the public,the power plant has gradually increased the protection of generator transformers.From a theoretical point of view,this paper analyzes the protection principle of power plant generator transformer and the importance of relay protection,and proposes several relay protection methods,for reference.
