Reactive equipment control method, system, equipment, and storage medium

Abstract

The invention discloses a control method, a system, a device and a storage medium of a reactive power equipment. The continuous reactive power reserve benefit coefficient IndexQ, which embodies the continuous reactive power reserve value, is obtained to measure the value of the continuous reactive power reserve according to different transmission power of a line. The invention utilizes the continuity of the IndexQ, which contains the continuous reactive power reserve benefit factor. Discrete Reactive Power Compensation Coordination Optimization Model for Continuous, discrete reactive power compensation, realizing the control of continuous reactive power equipment and discrete reactive power equipment, and realizes the coordination of economy and security of power network, Guaranteeing thesafe and stable operation of power network, It overcomes the technical problem that the existing coordination methods of continuous reactive power equipments and discrete reactive power equipments donot consider the continuous reactive power reserve capacity, or consider the continuous reactive power reserve capacity, but do not consider the benefit difference of continuous reactive power reservecapacity under different operation conditions, resulting in poor reactive power compensation effect.

Description

technical field [0001] The invention relates to the field of reactive power compensation, in particular to a control method, system, device and storage medium of reactive power equipment. Background technique [0002] Reactive power compensation: The full name of reactive power compensation is a technology that plays a role in improving the power factor of the power grid in the power supply system, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the power supply environment. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid. On the contrary, if it is improperly selected or used, it may cause many factors such as power supply system, voltage fluctuation, and harmonic increase. [0003] In recent years, large-scale wind power generation has been greatly developed. However, the connection of wind farms will pose a threat to the s...

Problems solved by technology

[0004] At present, most of the coordination methods of continuous reactive power equipment and discrete reactive power equipment do not consider the continuous reactive power reserve capacity, or consider the continuous reactive power reserve capacity, but do not consider the benefit difference of the continuous reactive power reserve capacity under different operating conditions. As a result, the effect of reactive power compensation is not good, and the following three problems are prone to occur:

[0005] (1) If too much consideration is given to the benefits of continuous reactive power reserve, continuous reactive power equipment will be kept as reactive power reserve as possible, so that discrete reactive power equipment can complete most of the reactive power adjustment tasks, which will lead to frequent switching of discrete equipment;

[0006] (2) If the benefits of the continuous reactive power reserve are not considered enough, the continuous reactive power equipment will be given priority to complete the reactive power adjustment task, which will lead to insufficient continuous reactive power reserve;

[0007] (3) The same benefits are considered in all operating conditions, and the value difference of continuous reactive power reserve under different operating conditions cannot be reflected
