柴油发电机组调试试验的过程和内容

来源:https://www.huannengpower.cn/ 文章作者:济柴环能 发布时间:2022-11-24
鉴于应急柴油发电机系统在核电站中的重要性,在应急柴油发电机安装后的调试阶段,应进行系统的功能调试和试验。
In view of the importance of the emergency diesel generator system in the nuclear power plant, the functional commissioning and test of the system should be carried out in the commissioning stage after the installation of the emergency diesel generator.
首先,需要验证辅助系统的功能,如冷却水、燃油等系统和回路,是否有泄漏或渗漏,并确保柴油发电机启动前油底壳、油箱和其他储油箱的液位显示在正常范围内,燃油泵和润滑油泵的出口压力和流量符合设计要求。并验证预热回路的功能满足柴油机热储备的要求。
First of all, it is necessary to verify the functions of auxiliary systems, such as cooling water, fuel oil and other systems and circuits, for any leakage or leakage, and ensure that the liquid level of the oil pan, oil tank and other oil storage tanks is displayed within the normal range before the diesel generator is started, and the outlet pressure and flow of the fuel pump and lubricating oil pump meet the design requirements. It is also verified that the function of preheating circuit meets the requirements of diesel engine thermal reserve.
接下来需要对柴油发电机组的电气部分进行调试和功能测试,比如测试柴油发电机组保护装置的可用性:确保电源正常,柜内设备齐全,参数设置符合设计要求,特别是要确保各类保护参数设置在要求的范围内,正确触发跳闸保护逻辑。
Next, the electrical part of the diesel generator set needs to be debugged and function tested, such as testing the availability of the diesel generator set protection device: to ensure that the power supply is normal, the equipment in the cabinet is complete, and the parameter settings meet the design requirements, especially to ensure that various protection parameters are set within the required range, and correctly trigger the trip protection logic.
前期准备工作完成后,应进行柴油发电机组的启动试验。本次试验还验证了应急柴油发电机组辅助系统在柴油机运行时的功能能够满足设计要求。但在本次试验中,柴油发电机组是空载运行的,本次启动是为了后续的带负荷试验,验证柴油机的可用性。
After the preliminary preparation, the diesel generator set shall be started. This test also verified that the functions of the auxiliary system of the emergency diesel generator set when the diesel engine is running can meet the design requirements. However, in this test, the diesel generator set operates without load. This startup is for the subsequent on load test to verify the availability of the diesel engine.
应急柴油发电机组带负荷试验前,应在静态条件下检查励磁调节系统的可用性,以验证空载条件下应急柴油发电机组中励磁电流与发电机定子电压之间关系的正确性,以及短路条件下励磁电流与发电机定子电流之间关系的正确性。
Before the on load test of the emergency diesel generator set, the availability of the excitation regulation system shall be checked under static conditions to verify the correctness of the relationship between the excitation current and the generator stator voltage in the emergency diesel generator set under no-load conditions, and the correctness of the relationship between the excitation current and the generator stator current under short-circuit conditions.
需要验证柴油发电机组在负载下的运行情况,以及紧急情况下各种启动方式的可靠性和时间响应。本文描述的柴油机功率异常波动是在柴油机机组全功率试验中发现的。
It is necessary to verify the operation of the diesel generator set under load, as well as the reliability and time response of various startup modes in emergency. The abnormal fluctuation of diesel engine power described in this paper was found in the full power test of diesel engine set.
