Method for improving unattended safety level of transformer station

Abstract

The invention relates to a method for improving unattended safety level of a transformer station, belonging to the power supply field. The method comprises the step of dividing a transformer station into three main parts to form three centralized control stations, namely a ninth main transformer station, a tenth main transformer station and a thirteenth transformer station, wherein the three centralized control stations respectively carry out centralized control on nearby transformer stations, that is the ninth main transformer station controls a fourth transformer station, a sixth transformer station, a seventh transformer station and a sixteenth transformer station, the ninth main transformer station controls a second transformer station, a third transformer station, an eleventh transformer station, a fourteenth transformer station and a fifteenth transformer station, and the thirteenth transformer station controls a first transformer station, a fifth transformer station, an eighth transformer station, a twelfth transformer station and a seventeenth transformer station. The method for improving the unattended safety level of the transformer station, disclosed by the invention, has the advantages of greatly improving stability of a monitoring system, improving the work efficiency of an operator, reducing the work load of electric power schedule, reducing labor demand, increasing efficiency and relieving the shortage of labors, and effectively ensuring safe and stable running of an electric power system.

Description

Technical field The [0001] The invention is widely used in power systems such as antihypertensive stations and substations. Background technique The [0002] With the sharp increase in the construction of the construction power supply load of 1.5 million tons of the Tai Istang project, the pressure reduction station was surged to 19 stations from the original 9 stations.It turned out that there were 9 antihypertensive stations: 1 220kv antihypertensive station, 8 110kV antihypertensive stations, and now expanded to 4 220kV lower -pressure stations, 12 110kV antihypertensive stations, 1 35kV lower -pressure station, 2 10kV changesPower station.The scale of the power network is getting larger and larger, but the operators have not increased. According to the personnel configuration of each antihypertensive station, 90 people need to be equipped with 90 people.It directly affects the normal operation of the grid. [0003] The scale of the power grid expanded, and the number of time...

Problems solved by technology

The operation between stations is frequent, because different step-down stations belong to different operating areas, resulting in increased contact confirmation work, and the probability of misoperation also increases, such as the erroneous power transmission of the 110KV second drop line with ground knife Operation accidents caused fluctuations in the power grid, which seriously affected the production of the secondary unit and caused huge losses
