TKL-11型励磁调节器的失控问题及改进措施

Problems of Losing Control and Improvement Measure of TKL-11 Excitation Regulator

针对我国早期开发而现今仍有大量应用的TKL-11型水轮发电机组励磁调节器在甩负荷时的失控现象进行了分析,发现在此工况下,该装置的失控现象有着一定的必然性,通过在原控制电路触发极并联一锁相回路,可消除失控现象。该措施在多台机组应用,均获成功。

In the case of load rejection in units,the excitation regulator of TKL-11 hydro-generator set,which was developed in the early stage of our country,is abnormal regulation.According to the analysis of this phenomenon,it is found that the device runs out of control under this condition has inevitability.The runaway phenomenon can be eliminated by parallel connection of a phase-locked loop with the trigger pole of the original control circuit.This measure has been successfully applied in many units.
