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)電機啟動前油底殼、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)計要求。并驗證預(yù)熱回路的功能滿足柴油機熱儲備的要求。

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

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)進行柴油發(fā)電機組的啟動試驗。本次試驗還驗證了應(yīng)急柴油發(fā)電機組輔助系統(tǒng)在柴油機運行時的功能能夠滿足設(shè)計要求。但在本次試驗中，柴油發(fā)電機組是空載運行的，本次啟動是為了后續(xù)的帶負(fù)荷試驗，驗證柴油機的可用性。

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

需要驗證柴油發(fā)電機組在負(fù)載下的運行情況，以及緊急情況下各種啟動方式的可靠性和時間響應(yīng)。本文描述的柴油機功率異常波動是在柴油機機組全功率試驗中發(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.
