Dynamic Evaluation Technology of Measurement Performance Group of High Voltage Transformer Based on Virtual Standard Device
摘要
Aiming at the problem that it is difficult to find abnormal conditions of Voltage transformer and the operation status is unknown, this paper proposes a dynamic evaluation technology for measuring performance group of high voltage transformer based on virtual standard. According to the strong electrical correlation relationship of Voltage transformer in substation, a virtual standard with high-precision time sequence true value is constructed. Based on the comparison between virtual standard value and actual secondary measurement value, the operation status evaluation of Voltage transformer is realized.
