Embodiment 1

[0056] A power supply path-based method for quickly removing the overload load of power grid equipment, comprising the following steps:

[0057] S1. Obtain the real-time load data of the equipment periodically, set the overload load limit according to the predefined equipment capacity, and judge whether the equipment is in the overload load state and overload load operation;

[0058] S11. Judgment of equipment overload load state: when the real-time active load of the equipment is greater than the overload load limit, it is determined that the equipment load is in the overload load state, and the calculation formula for the determination is

[0059] ΔP t =P t -P limit ,

[0060] Among them, P t is the real-time active load of the equipment at any moment, P limit is the overload load limit of the equipment, ΔP t is the overload of the equipment, when the equipment load is in the overload state, ΔP t >0;

[0061] S12. Judgment of equipment overload and load operation: ju...

Abstract

The invention discloses a method for quickly removing the overload load of power grid equipment based on a power supply path. The method firstly determines whether the equipment is in an overload load state and overload load operation; The power plan set removes the uncontrollable equipment set to form a controllable load equipment set; then combines the load equipment selection constraints to form a controllable equipment set; finally, through the concurrent control method, the overload load is quickly removed. In this way, by monitoring the overload status of power grid equipment, it assists dispatching and control personnel to improve the monitoring ability of power grid operation; it can effectively locate the scope of overload power supply, cut off the relevant downstream load equipment of power supply, and avoid cutting off load lines that are useless to eliminate overload, and reduce power outages for users range, which helps to improve user satisfaction; it can quickly and effectively realize overload load removal, prevent the expansion of the fault range, and ensure the safe and stable operation of the power grid.

Description

technical field [0001] The invention belongs to the technical field of smart grids, in particular to a method for quickly removing overload loads of grid equipment based on power supply paths. Background technique [0002] The safe production of electric power is not only related to the stability, benefit and development of the power system itself, but also directly affects the interests and safety of the majority of power users, the healthy development of the national economy, the stability of social order and the daily production and life of the people. With the rapid development of the national economy, the continuous progress of the society and the improvement of people's living standards, not only the corresponding development requirements are put forward for the electric power industry, but also higher requirements are put forward for the electric power safety production industry. [0003] With the rapid development of the local economy, the grid load in many areas inc...
