Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0031] Such as figure 1 As shown, a distribution network management and control method based on distribution network interconnection, which can be set in the distribution network centralized control device (distribution network coordination controller), specifically includes the following steps:

[0032] Step 1, collect data of each station area of ​​the distribution network, and analyze the working status of each station area.

[0033] The data of each station area of ​​the distribution network is monitored through smart terminals such as TTU, including operating data, power grid status, etc., and the data of each station area is sent to the centralized control device of the distribution netwo...

Abstract

The invention discloses a power distribution transformer power supply area interconnection-based power distribution network management and control method. The method comprises the following steps that: the data of each transformer power supply area of a power distribution network are collected, and the working state of each transformer power supply area is analyzed; in response to the low-load operation of the plurality of transformer power supply areas, a load concentration instruction is sent out, so that the load of the low-load transformer power supply areas is interconnected to other non-low-load transformer power supply areas; in response to the alternating current interconnection of the transformer power supply areas and the overload operation of a certain transformer power supply area, a load dispersion instruction is sent to disperse the load of the overload transformer power supply area to a non-overload transformer power supply area; and in response to the direct current interconnection of the transformer power supply areas and the overload operation of a certain transformer power supply area, a load support instruction is sent to transmit active power flow to the PCS ofthe overload transformer power supply area, or a power constraint instruction is sent to limit the active power flow of the PCS of the overload transformer power supply area. The invention further discloses a corresponding system. According to the method of the invention, load concentration is realized, so that low-load distribution transformers are relieved; load dispersion, load support or power constraint are realized, so that overload distribution transformers are adjusted, and the operation benefits of a power grid are effectively improved.

Description

technical field [0001] The invention relates to a distribution network management and control method and system based on the interconnection of distribution stations, belonging to the field of distribution network and electric power ubiquitous Internet of Things. Background technique [0002] The distribution network adopts the AC power distribution method, and usually adopts the closed-loop design and separate operation mode to supply power to each station area separately. The existing distribution network management and control methods have the following problems: 1. When low-load operation occurs in a certain area of ​​the distribution network, the existing method cannot alleviate the low-load distribution transformer; 2. When a high-load operation occurs in a certain area of ​​​​the distribution network During operation, the existing method cannot realize the adjustment of the overload distribution transformer. Contents of the invention [0003] The present invention ...
