海洋能多能互补智能供电系统总体设计

Abstract

为解决海洋能不稳定、难以实现独立或并网供电的问题，提出多能互补发电方案。本文所设计的海洋能多能互补智能供电系统综合利用波浪能、潮流能、海上风能和太阳能，填补了多能互补供电系统在海洋能利用领域的空白。该系统包括海洋能发电装置、并网控制柜、汇流开关柜、操控台和储能系统，可将多路海洋能发电装置的电力输入转为三相380 V/50 Hz交流输出，具有发电调度功能和可靠的系统安全保护功能，解决了海洋能多路输入、平稳输出的问题，实现了海洋能的并网供电，对海洋能的综合开发利用有着重要影响。 On account of its high instability, marine energy is difficult to generate electricity independently or realize electricity incorporation. To solve this problem, multi-energy complement electric scheme is proposed. The intelligent hybrid electricity system for marine energy in this paper utilizes wave energy, tidal energy, offshore wind energy and solar energy comprehensively, filling in gaps of pluripotent complementary power supply system in the use of marine energy. The intelligent electricity system is composed of marine energy power generation devices, gird-connected control cabinet, bus switch cabinet, console, and energy storage system. The power input of multipath marine energy power generation devices can be changed into three-phase AC output of 380 V/50 Hz. Power generation dispatching and system security function can be realized. The intelligent electricity system solves the stable output problem of marine energy, makes it possible to access the electric grid, and benefits the comprehensive development and utilization of marine energy.
