Problems solved by technology

[0003] The current power grid operation ticket system mainly relies on subjective experience for the correctness and safety of ticket issuance. Most of them rely on the logical judgment preset by the expert system and the intuitive analysis of the dispatcher after the ticket is issued. It cannot be done through calculation. Analysis to carry out scientific ope

Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] This embodiment proposes a security check method for operation tickets based on disturbance evaluation and trend analysis. The schematic diagram of the overall process is as follows figure 1 As shown, the following steps are implemented by computer:

[0034] 1) Operation ticket safety check data statistics;

[0035] In order to check the safety of the power grid operation ticket, not only the operation ticket information is needed, but also the power grid model, real-time operation mode data of the power grid, dispatching plan data and load forecast data. The operation ticket safety check data organization realizes the preparation of various data required, and provides a data basis for subsequent power flow analysis and stability calculation.

[0036] Firstly, the information that affects the grid topology is ex...

Abstract

The invention discloses an operation ticket security check method based on disturbance evaluation and trend analysis. The method comprises the following steps of (1) counting data; (2) performing calculation of trend and stability check; (3) performing disturbance evaluation on power grid scheduling operation; (4) analyzing stability trend before and after operation; and (5) giving an operation ticket security check conclusion and displaying. Due to the adoption of the method, the comprehensive security and stability analysis of a power grid scheduling operation ticket is realized, the influence of scheduling operation disturbance on power grid security is evaluated, the variation trend of the power grid security and stability levels before and after operation is analyzed, the technical support of security and stability analysis of the operation ticket is provided for scheduling operation personnel, and the security and stability levels of a power grid are raised.

Description

technical field [0001] The invention belongs to the field of power system scheduling operation and calculation analysis, and in particular relates to a method for checking safety of an operation ticket based on disturbance evaluation and trend analysis. Background technique [0002] The power grid dispatching operation ticket is an important management system to ensure the safe operation of the power grid. The power grid dispatching operation ticket is a strict operation procedure formulated to ensure the correct change of the equipment operation mode under the consideration of the system operation mode, protection cooperation, safety operation rules and other requirements. The existing operation ticket generation system often seldom considers the operation security. The main reason is that the existing operation ticket system is not connected with the real-time power grid monitoring system, and most of them are offline, without combining the actual operation status of the po...
