Online monitoring method for full life cycle of transformer substation direct-current system based on Internet of Things

Abstract

The invention discloses an online monitoring method for the full life cycle of a transformer substation direct-current system based on the Internet of Things. The method comprises the following stepsof: collecting historical data and monitoring data, introducing the collected historical data and monitoring data respectively into a training data input interface and a monitoring data input interface, introducing various data into a data preprocessing module for pretreatment, analyzing the equipment state model, running a state library, performing regression prediction, providing early warning and issuing early warning information. The invention further comprises a layered system framework, the system framework comprises an application layer, a network layer, an entity layer and a sensing layer, and the application layer comprises a transformer substation direct current system and a full-life-cycle online monitoring and diagnosis system. According to the invention, the system state can be comprehensively judged through historical data analysis, the judgment can be more precise, and full-cycle management is carried out on the transformer substation direct current system, the equipmentoperation condition and processing method are comprehensively mastered, an online monitoring and diagnosis platform for the full life cycle of the transformer substation direct current system is established, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of online monitoring, in particular to an online monitoring method for the whole life cycle of a DC system of a substation based on the Internet of Things. Background technique [0002] With the rapid development of the power system, there will be more and more unattended substations across the country. Since the substations are relatively scattered and inconvenient to maintain, this cannot guarantee the normal inspection of the substation system. In order to realize the transformation of the maintenance status of the DC system of the substation, the research and development of the automation of the DC system of the substation has become a topic of concern to the Chinese people. The online system inspection is in It came into being under this background and is one of the rapidly developing detection technologies. [0003] At present, the monitoring center can only get a small amount of signal upload for the...

Problems solved by technology

Since the substations are relatively scattered and inconvenient to maintain, this cannot guarantee the normal inspection of the substation system. In order to realize the transformation of the maintenance status of the DC system of the substation, the research and development of the automation of the DC system of the substation has become a topic of concern to the Chinese people. The online system inspection is in In this context, it emerged as the times require and has been rapidly developed as one of the detection technologies

[0003] At present, the monitoring center can only get a small amount of signal upload for the DC system part. The DC system often accumulates many large and small problems before carrying out comprehensive rectification. The reliability is very low. Many stations only encounter power failures in the whole station It was only after realizing the collapse of the DC system that DC system equipment has gradually developed towards automation, systematization, and integration. With the increasing number of substations and the shortage of operation and maintenance personnel, maintenance work has become difficult to take into account. The lack of factual information on the existing DC system also increases the difficulty of maintenance. The maintenance cycle for a single battery or charger is long and inefficient. not meeting people's demands
