瓦斯发电机组的电气保护一般设置有过载、高频低频、差动、接地、励磁故障等，不同的厂家保护配置有所不同。今天主要来讲讲瓦斯发电机组电气保护整定及传动试验相关内容事项。

The electrical protection of gas generator sets generally includes overload, high-frequency and low-frequency, differential, grounding, excitation fault, etc. The protection configurations of different manufacturers are different. Today we mainly talk about the electrical protection setting and transmission test of gas generator sets.

试验时参照燃机电气保护装置技术文件，对定值单的内容逐项进行核对，设置保护模块中机组发电机各侧的CT变比、PT变比、电流电压值及各种保护参数。

During the test, refer to the technical documents of the gas turbine electrical protection device, check the contents of the setting sheet item by item, and set the CT transformation ratio, PT transformation ratio, current and voltage values and various protection parameters at each side of the unit generator in the protection module.

调试时用继电保护测试仪对保护模块进行相应的模拟故障试验，使保护可靠动作，检查各插件面板指示灯动作及出口继电器输出情况，用万用表在端子排查该保护的所有跳闸出口接点动作是否正确，外部有连锁的接点检查连锁动作情况。

During commissioning, relay protection tester shall be used to conduct corresponding simulated fault test on the protection module to make the protection operate reliably. Check the action of indicator light on each plug-in panel and the output of outlet relay. Use a multimeter to check whether all tripping outlet contacts of the protection act correctly at the terminal. Check the interlocking action of external interlocking contacts.

一般应检查发电机保护动作后连锁跳闸出口高压开关、瓦斯气预处理系统输入及排空阀、厂区锅炉系统等连锁动作情况。

Generally, the interlocking actions of the high-voltage switch at the outlet of the interlocking trip, the input and vent valve of the gas pretreatment system, the boiler system in the plant area, etc. after the generator protection action should be mainly checked.

验证各系统逻辑动作的准确性及可靠性。试验过程中需要注意跳闸出口继电器输出接点极性应与外回路直流电源极性配合。

Verify the accuracy and reliability of the logic actions of each system. During the test, it shall be noted that the polarity of the output contact of the tripping outlet relay shall match the polarity of the external circuit DC power supply.

试验过程中送电、送气及其他工作事宜均由调试总负责人负责，做到各系统有序协调，专门的调试人员应参加调试各阶段工作的检查、交接验收等工作。

During the test, the general person in charge of commissioning shall be responsible for power transmission, gas transmission and other work to ensure orderly coordination of all systems. Special commissioning personnel shall participate in the inspection, handover and acceptance of work at each stage of commissioning.

瓦斯发电机组在试验过程时一旦发生瓦斯泄漏，严禁在运行状态下用铁质工具对泄漏点进行修理紧固，应停机后将设备或管道内瓦斯排尽后再做处理，同时在发电厂区域内严禁吸烟，严禁采用非防爆设备作业，严禁动火动焊作业。更多相关内容就来我们网站//www.gz-yanye.com进行留言咨询吧！

In case of gas leakage during the test of gas generator set, it is strictly forbidden to repair and fasten the leakage point with iron tools under the running state. The gas in the equipment or pipeline shall be drained after shutdown. At the same time, smoking is strictly prohibited in the power plant area, non explosion proof equipment is strictly prohibited, and hot welding is strictly prohibited.
