Problems solved by technology

In the existing dynamic environment monitoring system, communication power supply information and alarms can be collected and displayed by means of telemetry, remote signaling, etc., but the inventors found that fault judgment and hidden danger threshold analysis still need to be implemented manually, with a large workload and Misjudgment is prone to occur, which affects the timely positioning and analysis of hidden dangers and faults; in addition, the inventors also found that the existing power environment monitoring system is difficult to realize online monitoring of static physical quantities such as communication power circuit breakers and fuse capacity, and gradually deviates Insensitive to changes outside the normal range

Abstract

The invention belongs to the field of substation communication power supply analysis, and provides an intelligent hidden danger analysis system and method for a substation communication power supply.The hidden danger intelligent analysis system of the transformer substation communication power supply comprises: a protocol conversion module used for converting a communication protocol of the communication power supply so as to acquire real-time operation information of the communication power supply; an interconnection interface module which is used for communication between the power environment monitoring system and the fault diagnosis and analysis module; a fault diagnosis and analysis module which is used for calculating a rectification module capacity state, a rectification module current sharing state, a fuse capacity state and a cable capacity state based on the real-time operation information and the power environment information of the communication power supply to obtain a corresponding sub-health degree of the communication power supply, if any sub-health degree is 0, it is judged that the communication power supply has a hidden danger, otherwise, the health state of thecommunication power supply is judged according to comparison of the sub-health degree accumulation and a preset threshold value.

Description

technical field [0001] The invention belongs to the field of substation communication power supply analysis, and in particular relates to a hidden danger intelligent analysis system and method of substation communication power supply. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Due to the failure of the communication system, all serious events such as the interruption of the communication of the substation and the power outage of the computer room are all caused by the failure of the communication power supply. The reliable operation of the communication power supply has become the core factor affecting the safe operation of the power grid. In the existing dynamic environment monitoring system, communication power supply information and alarms can be collected and displayed by means of telemetry, remote signaling, etc., but the invento...
