Problems solved by technology

[0003] The utilization rate of multi-type distributed power regional coordinators is getting higher and higher, and they will generate heat to varying degrees during work. When the temperature rises, a series of adverse phenomena will occur: the temperature rises, which directly affects the loss of electric energy , will increase the loss of electric energy, and the temperature will rise, causing the surrounding insulation material equipment to age faster, and even easily causing fire accidents
[0004] The shell of the existing multi-type distributed power supply area controller is assembled from the upper and lower common aluminum alloy cover plates and the left and right common aluminum alloy side plates. In the actual production process, the joint surface of the shell and the shell is fixed by screws or riveted. , because the regional controller does not have an effective heat dissipation structure, resulting in a low service life

Embodiment 1

[0053] Example 1: At present, the distributed energy coordinated control technology of the distribution network is coordinated at different time scales through global optimization of energy management and regional autonomous control, so as to improve the robustness and economy of power grid operation. Its overall technical route is as follows: figure 1 As shown, through the study of the control index system of the distribution network to guide the coordinated control of active power of the distribution network, on this basis, a coordinated control method of active power based on the distribution network is proposed, and the corresponding regional controller is designed and developed.

[0054] refer to figure 2 The global energy management system of the distribution network collects the real-time operation data of the entire distribution network, including the operation data of each distributed energy generation, and calculates the global optimal control method according to th...

Embodiment 2

[0092] Embodiment 2: as Figure 6-Figure 10 As shown, a multi-type distributed power supply regional coordinator that facilitates heat dissipation, the controller includes an upper box assembly 100 and a lower box assembly 200, the upper box assembly 100 and the lower box assembly 200 are fixed by connecting pieces, and assembled into a box , A control circuit is installed in the box.

[0093] Specifically, the upper box assembly 100 includes a left plate 101, a rear plate 102 and a lower plate 103, one side of the left plate 101 is connected with the rear plate 102, and the other side perpendicular to it is connected with the lower plate 103, and the rear One side of the plate 102 is connected to the lower plate 103, and forms a pattern similar to a vertex formed by three surfaces through the left plate 101, the rear plate 102 and the lower plate 103;

[0094]The lower box assembly 200 comprises a right plate 201, a front plate 202 and an upper plate 203, one side of the rig...

Abstract

The invention discloses a layered distribution control method and an area controller. The control method comprises the steps of calculating a transformer station distribution network wire outlet control error; adjusting a PI regulator and performing fuzzification processing; and perfecting a distribution method. The area controller comprises the components of an upper housing assembly which comprises a left board, a back board and a lower board; a lower housing assembly which is connected with the upper housing assembly through a connector for forming the housing and comprises a right board, afront board and an upper board; and a heat radiating assembly which comprises a heat radiating fan and heat radiating holes, wherein the heat radiating holes are arranged on the back board and the front board, wherein the heat radiating fan is arranged in the upper housing assembly and is arranged at the heat radiating holes. Through a layered distribution method, stable and economic operation ofthe power distribution network is optimized. Through the heat radiating assembly of the area controller for facilitating heat radiation, heat in the device can be radiated. Furthermore high convenience and low cost are realized.

Description
