How to eliminate overvoltage of reactive power compensation controller

In the power industry, reactive power compensation controllers are widely used to control and regulate equipment in various aspects of the power system. But as it continues to be put into use, some questions about the controller also arise. For example, overvoltage problems will have an impact on the operation of the power system and the stability of the equipment. So, is there any way to eliminate overvoltage?
The answer is of course, because overvoltage is caused by the reactive power compensation controller generating reactive power through electric excitation, which will cause voltage fluctuations. When the load of the reactive power compensation controller suddenly decreases or disappears, it will cause the rated voltage to rise and form an overvoltage. This overvoltage can cause great damage to electrical equipment and even cause accidents.
Therefore, if you want to eliminate overvoltage problems, companies can do so through these methods:
First, by rationally designing the distribution network of the power system and appropriately distributing reactive loads, avoid the sudden reduction or disappearance of the load.
Secondly, install an overvoltage protection device to monitor voltage changes. Once overvoltage occurs, cut off the power supply in time to protect the safe operation of the equipment.
In addition, the probability of overvoltage is reduced by adjusting the parameters of the reactive power compensation controller. Specific methods include adjusting reactive power compensation capacity, reducing excitation current, etc. Through reasonable parameter adjustment, the operation of the reactive power compensation controller can be stabilized and the occurrence of overvoltage can be avoided.
In fact, the overvoltage problem of reactive power compensation controller is also a common power phenomenon and is not a big problem. As long as companies use the right methods and measures, this problem can basically be solved. Ensure the safe operation of the reactive power compensation controller and even the entire power system.
