漂浮直驱式波浪能发电装置的负载控制设计

摘要

Floating direct-drive type wave energy device is a new generation device, which converts wave energy into electrical energy by linear motor. Load control technology is one of the key technologies in the wave power generation. On the one hand, load control is able to adjust the running of the device .On the other hand, it can optimize the device efficiency. The load is adjusted automatically according to the voltage output of the linear motor. The load is divided into three levels, a basic load, two adjustable load. Tests showed that the load control system achieved the purpose of the hierarchical control aiming at the voltage. It has laid the foundation of hierarchical control aiming at the average wave height in real sea conditions.%漂浮直驱式波浪能装置是通过直线电机将波浪能转换成电能的一种新型发电装置.负载控制技术是波浪能发电中的关键技术之一.负载控制一方面可调整装置的运行状态,另一方面可优化装置的转换效率.负载控制系统可按照直线电机输出电压的大小自动调整装置的负载大小.负载分为3级:基本负载、一级负载、二级负载.试验表明,负载控制系统实现了按电压进行分级控制的目的,为实海况下按照平均波高分级控制打下了基础.
