摘要
合理开发利用潮流能有利于解决环境污染和能源不足问题。介绍了潮流能发电系统基本原理及结构组成,通过对5种常用的最大功率点跟踪控制策略分析比较,设计变步长的扰动控制算法,省去复杂的潮流能发电系统数学模型的推导过程。提出以秀山灌门水道为对象的潮流能发电系统,建立Simulink仿真模型,依据设计的控制策略,进行仿真,验证所设计的控制策略有效性,确保潮流能发电系统安全、可靠、稳定地运行。
Rational development and utilization of tidal current can help solve the problems of environmental pollution and energy shortage. This paper introduces the basic principle and structure of tidal current power generation system,and then based on the analysis and comparison of five common MPPT tracking control strategies,designs the variable step-length disturbance control algorithm to avoid the complicated mathematical model derivation process of tidal power generation system. Finally,the paper presents a tidal current power generation system based on Xiushan Guanmen waterway,and establishes a Simulink simulation model,using which to make simulation according to the designed control strategy. The paper also verifies the effectiveness of the designed control strategy to ensure the safe,reliable and stable operation of tide energy power generation system.
