Abstract

The invention relates to a power grid super power supply capability online control method and device. The control method comprises the following steps: obtaining real-time operation data of a power grid through an EMS energy management system; obtaining a topological relation and calculation nodes of a power grid through real-time operation data of the power grid, generating a power grid model according to the topological relation and the calculation nodes of the power grid, and drawing the power grid model into an electronic drawing by utilizing a drawing tool; carrying out load flow calculation according to the topological relation of the power grid and the real-time operation data of the power grid to obtain load flow data of each calculation node; presetting a super power supply overload condition for equipment in the power grid, and compiling an operation sequence table used for indicating the control priority; and searching the power flow data of the equipment in the power grid in real time, judging that the equipment is overloaded when the power flow data of one piece of equipment triggers a preset super power supply overload condition, and automatically generating and executing a control plan.

Description

technical field [0001] The invention relates to an online control method and equipment for power grid exceeding power supply capacity, belonging to the technical field of power grid control. Background technique [0002] For the power system in operation, the controller manually adjusts the load of related equipment according to the simulation calculation results of the EMS online power flow high-level application software. The power grid is generally closed-loop design, open-loop operation, connected through a hot standby switch, and generally presents a radiation type in structure. Load transfer is a common problem in power grid operation and scheduling. When encountering equipment overload, equipment failure, power outage, and equipment maintenance, In order to improve the reliability of power supply to users, controllers generally rely on scheduling experience or rough manual calculations, and then perform load transfer and restore power supply to out-of-power loads. At...
