对燃气发电机组实施强行励磁能行吗?

返回 2022.09.06 来源:http://www.huannengpower.com
燃气发电机组的应用过程中,我们会发现一些用户会对燃气发电机组实施强行励磁。很多人其实都不知道什么是强行励磁?进行励磁时,应考虑哪些因素?不当操作会造成什么危害?下面,小编将为大家简单介绍一下。
During the application of gas-fired generator sets, we will find that some users will forcibly excite the gas-fired generator sets. In fact, many people do not know what is forced excitation? What factors should be considered when exciting? What harm will improper operation cause? Next, Xiaobian will give you a brief introduction.
为了提高燃气发电机组运行系统的稳定性,在短路故障切除之后电压能迅速恢复到正常状态,要求电压下降到一定数值时,燃气发电机组的励磁能立即增加,所以燃气发电机组组要实行强行励磁。
In order to improve the stability of the operating system of the gas-fired generator set, the voltage can quickly return to the normal state after the short-circuit fault is removed. When the voltage drops to a certain value, the excitation energy of the gas-fired generator set will increase immediately. Therefore, the gas-fired generator set must be forced to excite.
励磁动作就是由继电器自动将励磁机回路的磁场调节电阻短接,或由燃气发电机组的自动调整励磁装置自动迅速调整使励磁机在大值电压下工作,以足够的励磁电流供给燃气发电机组。
The excitation action is to automatically short-circuit the magnetic field regulation resistance of the exciter circuit by the relay, or automatically and rapidly adjust the excitation device of the gas generator set to make the exciter work under high voltage and supply sufficient excitation current to the gas generator set.
燃气发电机组的强行励磁只有在励磁倍数较高,励磁电压上升速度较快,励磁时间足够的条件下才能发挥应有的作用。
The forced excitation of gas-fired generator set can only play its due role under the conditions of high excitation multiple, fast rise speed of excitation voltage and sufficient excitation time.

因此,燃气发电机组的励磁因励磁而加到值时,在1分钟之内不得干涉励磁的动作,在1分钟之后,则应立即采取措施,减低燃气发电机组定子和转子电流到正常允许的数值。
Therefore, when the excitation of the gas generator set is added to the value due to excitation, the excitation action shall not be interfered with within 1 minute. After 1 minute, measures shall be taken immediately to reduce the stator and rotor currents of the gas generator set to the normal allowable values.
励磁动作后,如果不返回,磁场电阻长时间被短接,在燃气发电机组正常运行时,转子将承受很高的电压而受到损伤。
After the excitation action, if it does not return, the field resistance will be short circuited for a long time, and the rotor will bear a high voltage and be damaged during the normal operation of the gas generator set.
可以看出,不返回的话会对燃气发电机组产生较大伤害,因此,建议大家要根据燃气发电机组运行状况,在保证正常运行的前提下,可以将不返回的励磁装置切除,查明原因,排除故障后再投入运行。更多注意事项就来我们网站http://www.huannengpower.com咨询吧!
It can be seen that failure to return will cause great harm to the gas-fired generator set. Therefore, it is recommended that the excitation device that does not return can be cut off according to the operating condition of the gas-fired generator set on the premise of ensuring normal operation, find out the cause, and put into operation after troubleshooting.
