SELF-ADJUSTING VOLTAGE FILTERING TECHNIQUE COMPENSATING FOR DYNAMIC ERRORS OF CAPACITIVE VOLTAGE TRANSFORMERS. |
摘要 |
A method of digitally correcting the raw output voltage from a Capacitive Voltage Transformer (CVT) with the intent to remove transient components impacting on transient accuracy of protection function. A typical CVT is represented using three parameters in the linear CVT model. A digital filter designed based on the three parameters and incorporating a dedicated mechanism to ensure numerical stability of the former. A method of self-adjusting the said filter based on system events and performed after the method has been deployed in the field and supplied from a specific CVT.
