The reactive power compensation system works normally, but it is still stressed
answer:
Our company's products are "low voltage reactive power compensation" products, but when the load rate of the user is low, the power factor of the high voltage measurement and measurement is lower because the inductive reactive power of the transformer itself accounts for a larger proportion of the total reactive power. Required value - It is recommended that the customer minimize the time of low load operation.
The voltage and current phase sequence is wrong, the controller shows that the power factor reaches the required value, but the actual power factor is under-compensated or over-compensated - check the controller sampling phase sequence, preferably there is a "matching terminal" or other high precision The power factor table is used as a control.
