Problems solved by technology
[0004] In the prior art, there have been researches on the status monitoring of power equipment, but there is no monitoring system for substations in harsh environments such as deep underground, hot surroundings, high humidity, and heavy air salt, so the operation of underground substations is reliable. Sexuality and safety cannot be effectively guaranteed

The invention discloses an underground substation state monitoring and reliability analysis method and system. The method comprises the following steps: carrying out monitoring on environment parameters, and carrying out statistics and correlation analysis on the recorded environment parameters to obtain a first result; extracting data in a distributed control system of a substation to a database server and carrying out correlation analysis and reliability assessment to obtain a second result; monitoring parameters of electrical equipment and carrying out analysis and fault probability prediction to obtain a third result; and carrying out early warning and alarming according to the first result, the second result and the third result. The method and system can carry out state monitoring and analysis prediction on severe environment of the underground substation, thereby ensuring operation reliability and safety of the underground substation.
Description
technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a method and system for state monitoring and reliability analysis of an underground substation. Background technique [0002] For underground substations, the heat dissipation capacity will be much lower than that of substations on the surface, therefore, in this case, the increase of operating temperature is the main reason for the failure of power equipment, and, in order to avoid fire and environmental pollutants, it should be Dry-type transformers and fire insulation are recommended. In order to ensure the safety and reliability of underground substations, the power equipment and environment need to be monitored and managed in real time. [0003] Since the 1990s, the condition monitoring of substations has become one of the most important tasks. Condition monitoring and diagnosis must meet two requirements: the first is to be able to predict ini...
