Abstract

The invention discloses a remote online transformer substation monitoring and state evaluation method, and belongs to the technical field of power grid communication. The method comprises the steps of data monitoring, data collection, state evaluation and state release. A WEB server receives transformer substation state evaluation determined by an application server and releases a notice to a worker of a transformer substation. No on-site construction can be performed, the transformer substation equipment state can be determined through remote evaluation, an existing manual multi-point blind inspection mode is ended, and the method has the advantages of being high in automation degree, high in efficiency and rapid in reaction.

Description

technical field [0001] The invention belongs to the technical field of power grid communication, and in particular relates to a method for remote on-line monitoring and state evaluation of a substation. Background technique [0002] The substation is the key link of power transmission, and the transformer and circuit breaker are the most important equipment in the substation. If the transformer and circuit breaker fail to be diagnosed and controlled in time and accurately, it will bring huge losses to the power system and national economic production. Loss. [0003] The biggest hazard of the transformer comes from the short-circuit impact current, which has the characteristics of strong concealment, great destructiveness, and high occurrence rate. When the power system fails, due to the inherent operating time of the circuit breaker and related automatic devices, the fault point cannot be removed at zero time. , the transformer will inevitably be impacted by short-circuit c...
