1、焦化發(fā)電機(jī)組調(diào)速裝置有故障，使焦化發(fā)電機(jī)供油量忽大忽小，造成發(fā)電機(jī)組轉(zhuǎn)速不穩(wěn)定，使發(fā)電機(jī)輸出電壓和頻率引起波動(dòng)。

1. The speed control device of the coking generator set has a malfunction, causing the oil supply of the coking generator to fluctuate, resulting in unstable speed of the generator set and causing fluctuations in the output voltage and frequency of the generator.

　　2、勵(lì)磁電路中，電壓調(diào)節(jié)整定電位器接觸不良或接線松動(dòng)，旋轉(zhuǎn)整流器接線松動(dòng)，使勵(lì)磁電流忽大忽小，引起發(fā)電機(jī)輸出電壓不穩(wěn)定。

2. In the excitation circuit, poor contact or loose wiring of the voltage regulation setting potentiometer, loose wiring of the rotating rectifier, causing the excitation current to fluctuate, resulting in unstable output voltage of the generator.

　　3、勵(lì)磁繞組對(duì)地絕緣受損，電機(jī)運(yùn)行時(shí)繞組時(shí)而發(fā)生接地現(xiàn)象使電壓波動(dòng)。

3. The insulation of the excitation winding to the ground is damaged, and the winding sometimes experiences grounding during motor operation, causing voltage fluctuations.

　　4、自動(dòng)電壓調(diào)節(jié)器(AVR)勵(lì)磁系統(tǒng)電路有故障，使AVR對(duì)勵(lì)磁電流控制不穩(wěn)定。

4. The automatic voltage regulator (AVR) excitation system circuit has a fault, which makes the AVR unstable in controlling the excitation current.
