Power substation busbar voltage real-time monitoring method

Abstract

The invention discloses a power substation busbar voltage real-time monitoring method. The method includes the following steps of dividing the voltages of busbars into N types, and setting different voltage qualified ranges for the voltages of all types of busbars, periodically collecting the voltages of the busbars of a target power substation, and generating corresponding warning according to the collected voltages of the busbars. An existing power substation data collecting and monitoring control system is sufficiently used; on the premise of extremely less increasing hardware devices, thevoltages of the busbars of the power substation are monitored in real time mainly through software, and the assessment requirements of the State Grid Corporation of China for the voltage qualified rate can be met for the power substation at extremely low refitting cost.

Description

technical field [0001] The invention relates to the technical field of busbar voltage monitoring, in particular to a method for real-time monitoring of busbar voltage in a substation. Background technique [0002] At present, the national grid is more and more strict in the assessment of the qualification rate of substation voltage. For some substations that use natural energy to generate electricity, due to the uncertainty of the geographical environment, the voltage fluctuates greatly, making voltage control more difficult. For example, the Lishui area of ​​Zhejiang Province is located in a mountainous area, so most of the substations are used for hydropower generation. Due to the instability of the water flow, the voltage of the substation fluctuates greatly, making voltage control more difficult. At present, there is a lack of methods dedicated to bus voltage monitoring, resulting in the voltage qualification rate of some substations using natural energy to generate ele...

Problems solved by technology

For some substations that use natural energy to generate electricity, due to the uncertainty of the geographical environment, the voltage fluctuates greatly, making voltage control more difficult.

For example, Lishui, Zhejiang is located in a mountainous area, so most of the substations are used for hydropower generation. Due to the instability of the water flow, the voltage of the substation fluctuates greatly, making voltage control more difficult.

At present, there is a lack of methods dedicated to bus voltage monitoring, resulting in the voltage qualification rate of some substations using natural energy to generate electricity cannot meet the assessment requirements of the State Grid
