Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] Such as Figure 1-Figure 3 , an integrated automatic voltage control method for prefectures and counties, said method comprising the following steps:

[0049] Step 1: Obtain real-time data required for grid model, control model and automatic voltage control;

[0050] Step 2: Carry out optimal calculation of voltage and reactive power in districts, counties, build a control strategy system, and obtain the control quantity of factories and stations in districts and counties;

[0051] Step 3: Centrally distribute the obtained control quantities to prefectural and county factories and stations for execution through the pre-communication of the dispatching automation system;

[0052] Step 4: Perform partition monitoring and partition management assessment statistics;

[0053] Step 5: When the voltage control period arrives, return to the cycle for period...

Abstract

The invention provides to a prefecture-county integrated automatic voltage control method. The control method comprises the following steps of: obtaining a power grid model, a control model and real-time data required for automatic voltage control; carrying out prefecture and county regional voltage idle work optimization calculation and constructing a control strategy system to obtain the controlling quantity of prefecture and county plant stations; distributing the obtained controlling quantity to a prefecture and county plant stations to be executed in a centralized manner through the prepositive communication of a scheduling automatic system; carrying out regional monitoring and regional management examining statistics; and returning for circulation so as to carry out periodic control monitoring and statistics when the voltage control period is reached. A prefecture-county shared automatic voltage control system more reasonably effectively utilizes various idle work adjustment and voltage control measures in a power grid, the construction investment of the system is reduced, and the system maintenance management is flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of automatic voltage control of electric power systems, and in particular relates to an automatic voltage control method integrated by districts and counties. Background technique [0002] The automatic voltage control AVC (automatic voltage control) system is a computer-based global voltage automatic closed-loop control system for modern power systems. Optimize the closed-loop control to ensure the grid voltage quality is qualified, realize reactive power layered and partitioned balance, and reduce network loss. [0003] In recent years, AVC systems have been more and more widely used in power grids at all levels. With the improvement of automation levels in various places, AVC systems have not only been applied in provincial and regional power grids, but also in some county-level power grids. Access and use step by step. For regional power grids with AVC systems at both prefecture and county levels, in o...
