發(fā)電機是一種將機械能轉(zhuǎn)化為電能的設(shè)備，用于產(chǎn)生電力供電或備用電源。然而，由于長時間運行或其他原因，發(fā)電機可能出現(xiàn)各種故障。下面是一些常見的發(fā)電機故障以及對應(yīng)的解決方案。

　　A generator is a device that converts mechanical energy into electrical energy, used to generate electrical power or backup power. However, due to prolonged operation or other reasons, the generator may experience various malfunctions. Here are some common generator faults and corresponding solutions.

　　1發(fā)電機進風(fēng)溫度異常升高

　　1. Abnormal increase in inlet air temperature of generator

　　處理：

　　handle:

　　如果發(fā)電機出風(fēng)溫度、定子線圈溫度未超過規(guī)定時，可不降低發(fā)電機的出力，但應(yīng)查明原因，及時調(diào)整；當(dāng)超過規(guī)定值時，應(yīng)先降低發(fā)電機出力再進行檢查處理。

　　If the outlet air temperature and stator coil temperature of the generator do not exceed the specified limits, the output of the generator may not be reduced, but the cause should be identified and adjusted in a timely manner; When the specified value is exceeded, the generator output should be reduced first before inspection and handling.

　　2發(fā)電機線圈和鐵芯溫度異常升高

　　2. Abnormal increase in temperature of generator coils and iron cores

　　處理：

　　handle:

　　如果超過規(guī)定值時，應(yīng)迅速降低負(fù)荷。

　　If the specified value is exceeded, the load should be quickly reduced.

　　迅速檢查冷卻空氣溫度，并檢查濾塵器是否堵塞；

　　Quickly check the temperature of the cooling air and check if the dust filter is clogged;

　　檢查空冷器出入口閥門是否關(guān)閉。

　　Check if the inlet and outlet valves of the air cooler are closed.

　　3發(fā)電機過負(fù)荷

　　3 Generator overload

　　發(fā)電機允許短時過負(fù)荷運行，過負(fù)荷的參數(shù)及時間按下表確定：

　　The generator is allowed to operate under short-term overload, and the parameters and time of overload are determined according to the following table:

　　過負(fù)荷時，要在規(guī)定的時間內(nèi)把負(fù)荷電流降至允許值內(nèi)，同時還要監(jiān)視發(fā)電機各部溫度不超標(biāo)。

　　When overloaded, the load current should be reduced to the allowable value within the specified time, and the temperature of each part of the generator should be monitored to ensure that it does not exceed the standard.

　　4發(fā)電機三相不平衡電流超標(biāo)

　　The three-phase unbalanced current of the generator exceeds the standard

　　處理：

　　handle:

　　發(fā)電機三相不平衡電流超過規(guī)定時，應(yīng)首先檢查是否由于互感器回路故障引起，否則應(yīng)降低定子電流使其不超過規(guī)定值，同時還應(yīng)嚴(yán)密監(jiān)視發(fā)電機各部溫度，當(dāng)發(fā)現(xiàn)溫度異常升高，不平衡電流增加時，應(yīng)緊急解列停機。如果并網(wǎng)運行，不平衡電流沒有超過額定值10%，減小外送有功，看不平衡電流是否變小，如果變小，是外網(wǎng)引起的。可以維持運行?；驍嚅_外網(wǎng)。

　　When the three-phase unbalanced current of the generator exceeds the specified value, the first thing to check is whether it is caused by a fault in the transformer circuit. Otherwise, the stator current should be reduced to not exceed the specified value. At the same time, the temperature of each part of the generator should be closely monitored. When the temperature rises abnormally and the unbalanced current increases, emergency disconnection and shutdown should be carried out. If the unbalanced current does not exceed 10% of the rated value during grid connected operation, reduce the external active power and see if the unbalanced current decreases. If it decreases, it is caused by the external grid. Can maintain operation. Or disconnect from the external network.

　　Refer to the instructions of other meters and check if it is caused by damage to the instrument itself or its primary and secondary circuits. If the secondary circuit wires are damaged, try not to change the operation mode of the generator as much as possible; If it affects the normal operation of the generator, the load should be reduced or the machine should be shut down according to the actual situation.

　　20發(fā)電機震蕩與失步

　　20 Generator Vibration and Out of Step

　　現(xiàn)象：

　　Phenomenon:

　　發(fā)電機正常運行時發(fā)出的功率和用戶的負(fù)荷功率是平衡的，發(fā)電機和系統(tǒng)都在穩(wěn)定狀態(tài)下運行。當(dāng)系統(tǒng)中發(fā)生某些重大擾動時，發(fā)電機與用戶的有功平衡將遭到破壞。此時必須立即改變發(fā)電機的輸出功率。

　　The power generated by the generator during normal operation is balanced with the load power of the user, and both the generator and the system are operating in a stable state. When significant disturbances occur in the system, the active power balance between the generator and the user will be disrupted. At this point, the output power of the generator must be immediately changed.

　　但由于發(fā)電機轉(zhuǎn)子的轉(zhuǎn)動慣性作用，汽輪機的調(diào)速器的動作需要一定的延時，故改變發(fā)電機的功率就需要有一個過程，在這個過程中，發(fā)電機的功率與用戶的功率不能平衡，就會破壞發(fā)電機穩(wěn)定運行，使發(fā)電機發(fā)生振蕩。

　　However, due to the rotational inertia of the generator rotor, the action of the turbine governor requires a certain delay, so changing the power of the generator requires a process. During this process, the power of the generator cannot be balanced with that of the user, which will disrupt the stable operation of the generator and cause oscillation.

　　處理：

　　handle:

　　如果事故不嚴(yán)重，汽輪機調(diào)速動作較靈敏則發(fā)電機的電流、電壓及功率經(jīng)短時間波動后，會恢復(fù)到功率平衡，如果事故很嚴(yán)重，汽輪機的調(diào)速器的動作很遲鈍，則會使個別發(fā)電機與系統(tǒng)之間發(fā)生激烈振蕩，另一瞬間又從系統(tǒng)吸收功率，這種功率來回傳遞，可能發(fā)展到使發(fā)電機與系統(tǒng)之間失去同步。

　　If the accident is not serious and the speed regulation action of the steam turbine is sensitive, the current, voltage, and power of the generator will return to power balance after a short period of fluctuation. If the accident is serious and the speed regulation action of the steam turbine is slow, it will cause intense oscillations between individual generators and the system, and at another moment absorb power from the system. This power is transmitted back and forth and may develop into a loss of synchronization between the generator and the system.
