Embodiment Construction

[0040] On the whole, there are three types of power grid control strategies: peer-to-peer control, master-slave control and hierarchical control. According to the control strategy requirements of the distributed power grid, the present invention designs a three-layer control structure, and divides the time scale of each layer control, and accordingly designs each layer communication network. Such as figure 1 As shown, the distributed grid communication system first adopts a three-layer architecture, which is the control center layer at the top, the grid management layer at the middle layer, and the grid component layer at the bottom.

[0041] The control center layer is a regional (such as city-level) distributed power grid control center, which realizes the operation monitoring and coordinated control of all power grid substation systems in the region, and coordinates the operation with the traditional large power grid. Set the control center layer in the prefectural and cou...

Abstract

The invention discloses a smart grid communication method comprising a top control center layer, a middle grid management layer and a bottom grid element layer. The grid center communicates with a distribution network and at least one grid element via the Ethernet. An in-station local area network is arranged in the grid management layer to realize communication between in-station equipment of the grid management layer. The in-station equipment includes a database server, a server, a workstation, a communication server, and a communication front machine. The in-station local area network communicates with the control center layer via the Ethernet. The method is compatible with grid elements with different communication interfaces through the communication front machine, and signal adjustment and correction is carried out at both the transmitter end and the receiver end of the grid to ensure high-accuracy signal transmission.

Description

technical field [0001] The invention belongs to the field of grid data communication, and in particular relates to a smart grid communication method. Background technique [0002] In recent years, clean and renewable energy power generation technologies such as solar energy, wind energy, and biomass energy have basically matured. The use of distributed power generation technology can improve power generation efficiency and power supply reliability, and can provide users with green power according to local conditions, realizing "nearby power generation at the user's side" use" to promote its large-scale application. [0003] The power grid control system is the core of the power grid. It monitors the operation status of the entire power grid system, and controls and manages the components of the power grid according to the system control strategy. [0004] Following the analog instrument control system, centralized digital control system, and distributed control system, dist...
