The invention discloses a method and system for linkage monitoring of busbar voltage in a power supply area, which relates to the technical field of power grid operation and maintenance, and interacts with the power grid topology connection relationship of PAS application in dispatching automation system and the busbar voltage of each substation in SCADA application to monitor the power grid The power supply area is divided, and the real-time value of the voltage collection points of all the busbars in each substation in the divided power supply area is collected, and the voltage distribution of the collection points of different voltage levels is displayed by punctuating the voltage level ring to form a power supply area The unique voltage linkage monitoring interface monitors and controls the overall voltage operation of different power supply areas during the operation of the power supply network, breaking the previous limitation that operators can only individually adjust the bus voltage of a single substation through the voltage limit alarm , through the way of regional linkage to improve the quality of voltage operation as a whole, the voltage qualification rate can be quickly improved.
Description
technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to a method and a system for monitoring the linkage of busbar voltage in a power supply area. Background technique [0002] The power grid voltage qualification rate is an important reference index for power grid operation to ensure the power supply quality and power supply reliability of power grid user loads. [0003] In the current power grid operation structure, the regional power grid takes 220kV substations as the skeleton, each 220kV substation supplies power to several 110kV substations, and finally forms a radial grid to supply power to users. Taking the 220kV substation as the center, the power supply range corresponding to the 110kV substation below it becomes an area. In the process of voltage monitoring, the grid power system dispatcher can only control the voltage in real time through the voltage data collection of a single substation and ...
