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.

，需要驗(yàn)證輔助系統(tǒng)的功能，如冷卻水、燃油等系統(tǒng)和回路，是否有泄漏或滲漏，并確保柴油發(fā)電機(jī)啟動(dòng)前油底殼、油箱和其他儲油箱的液位顯示在正常范圍內(nèi)，燃油泵和潤滑油泵的出口壓力和流量符合設(shè)計(jì)要求。并驗(yàn)證預(yù)熱回路的功能滿足柴油機(jī)熱儲備的要求。

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.

接下來需要對柴油發(fā)電機(jī)組的電氣部分進(jìn)行調(diào)試和功能測試，比如測試柴油發(fā)電機(jī)組保護(hù)裝置的可用性:確保電源正常，柜內(nèi)設(shè)備齊全，參數(shù)設(shè)置符合設(shè)計(jì)要求，特別是要確保各類保護(hù)參數(shù)設(shè)置在要求的范圍內(nèi)，正確觸發(fā)跳閘保護(hù)邏輯。

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.

前期準(zhǔn)備工作完成后，應(yīng)進(jìn)行柴油發(fā)電機(jī)組的啟動(dòng)試驗(yàn)。本次試驗(yàn)還驗(yàn)證了應(yīng)急柴油發(fā)電機(jī)組輔助系統(tǒng)在柴油機(jī)運(yùn)行時(shí)的功能能夠滿足設(shè)計(jì)要求。但在本次試驗(yàn)中，柴油發(fā)電機(jī)組是空載運(yùn)行的，本次啟動(dòng)是為了后續(xù)的帶負(fù)荷試驗(yàn)，驗(yàn)證柴油機(jī)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.

應(yīng)急柴油發(fā)電機(jī)組帶負(fù)荷試驗(yàn)前，應(yīng)在靜態(tài)條件下檢查勵(lì)磁調(diào)節(jié)系統(tǒng)的可用性，以驗(yàn)證空載條件下應(yīng)急柴油發(fā)電機(jī)組中勵(lì)磁電流與發(fā)電機(jī)定子電壓之間關(guān)系的正確性，以及短路條件下勵(lì)磁電流與發(fā)電機(jī)定子電流之間關(guān)系的正確性。

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.

需要驗(yàn)證柴油發(fā)電機(jī)組在負(fù)載下的運(yùn)行情況，以及緊急情況下各種啟動(dòng)方式的可靠性和時(shí)間響應(yīng)。本文描述的柴油機(jī)功率異常波動(dòng)是在柴油機(jī)機(jī)組全功率試驗(yàn)中發(fā)現(xiàn)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.
