一、發(fā)電質(zhì)量好
1、 Good power generation quality
由于發(fā)電機工作時只有旋轉運動，電調(diào)反應速度快，工作特別平穩(wěn)，發(fā)電機輸出電壓和頻率的精度高，波動小，在突加空減50%和75%負載時，機組集腋成裘駝行非常穩(wěn)定。優(yōu)于柴油發(fā)電機組的電氣性能指標。
As the generator only rotates during operation, the response speed of electric regulation is fast, and the operation is particularly stable. The accuracy of generator output voltage and frequency is high, and the fluctuation is small. When 50% and 75% load of air reduction is suddenly applied, the unit is very stable. It is superior to the electrical performance index of diesel generator set.
二、啟動性能好，啟動成功率高
2、 Good startup performance and high startup success rate
從冷態(tài)啟動成功后到滿負載的時間僅為30秒鐘，而規(guī)定柴油發(fā)電機啟動成功后3分鐘帶負載。燃氣輪發(fā)電機組可以任何環(huán)境溫度和氣候下保證啟動的成功率。
The time from successful cold start to full load is only 30 seconds, while the diesel generator is loaded 3 minutes after successful start according to international regulations. The gas turbine generator unit can guarantee the success rate of startup under any ambient temperature and climate.
三、噪聲低振動小
3、 Low noise and low vibration
由于燃汽輪機處于高速旋轉狀態(tài)，它的振動非常小，而且低頻噪聲優(yōu)于柴油發(fā)電機組。
As the gas turbine rotates at a high speed, its vibration is very small, and the low-frequency noise is better than that of the diesel generator set.

四、采用的可燃性氣體是清潔、廉價的能源
4、 The combustible gas used is clean and cheap energy
諸如：瓦斯氣，秸稈氣，沼氣等，以它們?yōu)槿剂系陌l(fā)電機組不僅運行可靠，成本低，而且能變廢為寶，不會產(chǎn)生污染。
For example, gas, straw gas, biogas, etc., the generator set using them as fuel is not only reliable in operation and low in cost, but also can turn waste into treasure without pollution.
發(fā)電機逆功率保護，用于保護汽輪機。當主汽門誤關閉或機爐保護動作關閉主汽門而發(fā)電機出口開關未跳閘時，發(fā)電機變成電動機運行狀態(tài)，此時發(fā)電機從系統(tǒng)吸收有功和無功，這種工況對發(fā)電機并無影響但由于鼓風損失，氣輪機尾部葉片有可能過熱，損壞尾部葉片而造成汽輪機事故。因此大機組不允許在這種工況下長時間運行，只允許運行幾分鐘。
Generator reverse power protection is used to protect steam turbine. When the main throttle valve is closed by mistake or the turbine and boiler protection action closes the main throttle valve but the generator outlet switch does not trip, the generator becomes the motor operation state. At this time, the generator absorbs active and reactive power from the system. This condition has no effect on the generator. However, due to the loss of air blowing, the tail blades of the turbine may overheat and damage the tail blades, causing turbine accidents. Therefore, large units are not allowed to operate for a long time under this working condition, only for a few minutes.
我國自行設計的發(fā)電機，以往不裝設逆功率保護，但采取以下措施：
In the past, generators designed by ourselves were not equipped with reverse power protection, but the following measures were taken:
(1)采用聯(lián)鎖方法。當主汽門關閉后，用主汽門輔助接點，經(jīng)延時切除發(fā)電機。上述方法雖然可行，但有不足之處，因為都不能正確地反映主汽門關閉情況。為了及時發(fā)現(xiàn)逆功率的異常工況，歐洲一些國家在發(fā)電機上配置有逆功率保護。逆功率保護其核心元件是逆功率繼電器。逆功率繼電器和功率方向繼電器相似，只是在功率方向相反時動作，及時發(fā)出信號或延時動作切機。
(1) Adopt interlocking method. When the main throttle valve is closed, use the auxiliary contact of the main throttle valve to cut off the generator after a delay. Although the above methods are feasible, they have shortcomings, because they can not correctly reflect the closure of the main throttle valve. In order to find out the abnormal working condition of reverse power in time, some European countries are equipped with reverse power protection on the generator. The core component of reverse power protection is reverse power relay. The reverse power relay is similar to the power direction relay. It only acts when the power direction is opposite and sends a signal in time or delays the action to cut off the machine.
(2)主汽門關閉后，在控制室內(nèi)發(fā)信號，如主汽門誤關閉，檢查之后可迅速恢復供汽，使機組正常運行，如幾分鐘恢復不了，可由值班員斷開發(fā)電機出口開關。
(2) After the main throttle valve is closed, send a signal in the control room. If the main throttle valve is closed by mistake, the steam supply can be recovered quickly after inspection to make the unit operate normally. If it cannot be recovered in a few minutes, the operator on duty can disconnect the generator outlet switch.
