Embodiment Construction

[0014] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0015] refer to figure 1 , figure 2 It is an embodiment of the island micro-grid system that integrates ocean current energy to generate electricity in the present invention. The island micro-grid system that integrates ocean current energy to generate electricity includes a fast control system in the station of the micro-grid control center station and a longer time-scale control system outside the station. The fast control system includes a time synchronization server, a central controller, a mode switching controller and an intelligent terminal of the interval microgrid in the station. The central controller, the mode switching controller and the intelligent...

Abstract

The invention discloses an island microgrid system integrated with ocean current energy power generation. The system comprises an in-station rapid control system and an out-station long-time scale control system of a microgrid control center station. A central controller, a mode switching controller and an in-station interval microgrid intelligent terminal of the in-station rapid control system are all connected with a process layer switch through optical fibers, and a time synchronization server controls the central controller, the mode switching controller and the in-station interval microgrid intelligent terminal to keep rapid synchronization. The out-station long-time scale control system comprises an energy management system and an out-station ocean current energy power generation device. An energy connection management system and the out-station ocean current energy power generation device are connected through an industrial-grade switch, and the central controller, the mode switching controller and the in-station interval microgrid intelligent terminal in the in-station rapid control system are also connected with the industrial-grade out-station switch of the longer-time scale control system. The system has the advantage that reliable and stable operation of the island microgrid system is ensured.

Description

technical field [0001] The invention relates to a sea-island micro-grid system that integrates ocean current energy to generate electricity. Background technique [0002] There are a large number of islands in my country, but most of them are far away from the mainland. The supply of energy such as electricity has become the main restrictive factor affecting the development of islands. By building a micro-grid system on the island, it can provide green power for island residents, solve the power supply problem of the island, and effectively improve the quality of electricity for users on the island. Therefore, the micro-grid power supply mode has developed rapidly on islands, and my country has built and put into operation a number of island micro-grid demonstration projects. In terms of energy composition, because wind power and photovoltaic power generation technologies are relatively mature, and islands generally have abundant wind and solar energy resources, and have st...
