Method for graphically monitoring running state of transformer of distribution network

Abstract

The invention discloses a method for graphically monitoring a running state of a transformer of a distribution network. The method comprises the following steps: displaying a real-time running state and data of a distribution transformer on a WEB window page in a graph manner after treating and calculating through a software system according to the running data of the monitored distribution transformer collected and sent back by an on-site measuring terminal device, wherein the graph shows the geographic information of the location of the distribution transformer and displays the current state of the distribution transformer with different colored blocks, and the colors of the colored blocks can directly reflect the high-low degree index of the load factor corresponding to the distribution transformer; and classifying and grading various distribution transformers according to the high-low degree index of the load factor and corresponding state color of each distribution transformer. By using the method, the running state of the transformer of the distribution network can be monitored in real time, so that the work loads of on-site inspection tour and long-time load measurement are greatly reduced, the hidden danger for the running of the distribution transformer is accurately and timely found out, a reforming plan can be made earlier, and the operation and maintenance levels of the device are improved.

Description

technical field [0001] The present invention relates to a method for graphically monitoring the operation status of distribution network transformers, in particular to a method for using a multi-dimensional information display module to graphically display the operation status of distribution network transformers in a WEB window and to monitor the status of distribution transformers in real time . Background technique [0002] Power supply enterprises are one of the important sectors of the national economy. With the rapid development of the national economy and the continuous improvement of people's living standards, the demand for electricity in our country is also increasing. In recent years, in the power system, the remote monitoring and control technology of substations, high-voltage transmission lines and other main network equipment has changed from the initial RTU equipment, SCADA (real-time data acquisition) system to the current integrated automation system, EMS sy...

AI Technical Summary

Problems solved by technology

In terms of low-voltage power distribution network, because the number of low-voltage power distribution lines, power distribution equipment, and load equipment is much larger than that of the main network, and the structure is more intricate, there is still no distribution network monitoring and control system with mature technology and stable performance. Widespread use, or limited to localized pilot applications

In particular, the monitoring technology for the operating status of distribution network transformers is not fully mature. The current inspection of the operating status of distribution network transformers is mainly through manual and regular on-site load measurement. Due to the large number of distribution network transformers, it is impossible to carry out all-weather inspections. Data monitoring records; and a distribution transformer only collects data for one day, which has low reference value and poor accuracy. susceptible to weather

The existing monitoring methods can only obtain the total load capacity and electricity consumption information of each city, township, and power supply station through regular reports, but it is impossible to understand the current load concentration in a certain area intuitively in real time and where the power consumption is. The load is high, and it is necessary to send personnel to the scene for a long time to investigate and then provide a preliminary assessment report, which is time-consuming and the data is not accurate enough
