Power grid dispatching operation safety accident level determination method and risk index calculation method

Abstract

The invention discloses a power grid dispatching operation safety accident level determination method and a risk index calculation method. The determination method comprises the steps of collecting calculation data of each stage of power grid dispatching operation; performing safety and stability simulation calculation of each stage of power grid dispatching operation according to the calculationdata; counting the load loss amount, the corresponding loss load equipment and the plant station to which the equipment belongs according to a simulation calculation result; calculating a power grid supply reduction load proportion, a user power failure proportion and a voltage loss station number caused by an electric power safety accident in a preset power grid range; and determining the safetyaccident level according to the power grid load reduction and supply proportion, the user power failure proportion and the voltage loss station number. According to the invention, online evaluation ofthe safety risk of the power grid dispatching operation is realized, a technical foundation is laid for pre-warning and pre-control of the power grid dispatching operation, potential safety hazards possibly caused by the dispatching operation are prevented, and safe and stable operation of the power grid is ensured.

Description

technical field [0001] The invention relates to a method for determining a safety accident level of power grid dispatching operation and a method for calculating a risk index, and belongs to the technical field of power grid dispatching. Background technique [0002] Power system dispatching operation is the basic means to adjust the operation mode of the power grid and deal with abnormalities and accidents of the power grid. How to ensure the safety of operation is a problem that must be dealt with in the daily work of power grid dispatching. With the continuous expansion of the scale of the power grid and the increasingly close connection between the power grids, the impact of improper dispatching operations on the safety and stability of the system may expand; Responsiveness also places higher demands. The existing operation ticket system generally focuses on anti-mistake checks of switching operations and power flow analysis. The safety and stability of the power grid a...

AI Technical Summary

Problems solved by technology

The existing operation ticket system is generally based on the anti-error verification of switching operation and power flow analysis. After the operation, the safety and stability of the power grid and its impact are mainly judged by the subjective experience of the operating personnel. There are high error rates, low work efficiency, and Risk avoidance is not timely and other technical problems
