Embodiment 1

[0043] In this embodiment, a framework diagram of an overall research idea is provided, please refer to figure 1 ,Such as figure 1 As shown, according to the basic structure and control idea of ​​hierarchical control, the working mechanism of various equipment at the station area level, line level and substation level is divided into UC unit control level, OC organization and coordination level, and CC central command level. Organize and refine policies.

[0044] based on figure 1 The framework diagram of the overall research idea shown in the figure, and the description of the voltage control method at the substation level, please refer to figure 2 , which shows a flow chart of the substation-level voltage control method provided by the present application, which may include the following steps:

[0045] Step S11: The low-voltage monitoring and early warning platform collects the operating voltage data in the distribution network to be controlled, and analyzes the collect...

Embodiment 2

[0092] Corresponding to the above method embodiments, this embodiment provides a substation level voltage control system, please refer to Figure 5 , the substation-level voltage control system includes: a low-voltage monitoring and early warning platform 51 , a three-phase simulation software system 52 for a distribution area, and an auxiliary decision-making system 53 for voltage quality management of a distribution network.

[0093] The low-voltage monitoring and early warning platform 51 is used to collect the operating voltage data in the distribution network to be controlled, and analyze the collected operating voltage data in the distribution network to be controlled, to obtain the cause of low voltage, its hazards, and the impact on electric energy measurement. The impact of the device and the low voltage treatment mechanism and prevention measures, and the cause of the low voltage, the hazard, the impact on the electric energy metering device, the low voltage treatment...

Abstract

The invention provides a method and a system for controlling transformer substation level voltages. The method and the system for controlling the transformer substation level voltages have the advantages that district level equipment is controlled, accordingly, terminal voltages of circuits of power distribution networks can be regulated and controlled, and the problem of low terminal voltages of existing circuits of existing power distribution networks can be effectively solved.

Description

technical field [0001] The present application relates to the field of electric power, in particular to a substation-level voltage control method and system. Background technique [0002] With the rapid development of the rural economy and the continuous acceleration of the urbanization process of the new countryside, especially the implementation of a series of policies for benefiting farmers such as "home appliances to the countryside", the demand for electric energy has grown rapidly. In recent years, the State Grid Corporation has gradually increased investment in distribution networks, but the level of distribution network construction in undeveloped areas is still lagging behind. Especially in rural areas, the contradiction between power supply capacity and economic development is prominent, new bottlenecks appear in power supply, and the problem of low voltage at the end of distribution network lines is serious. [0003] Therefore, how to solve the problem of low vol...
