光伏跟踪用开关磁阻电机动态步进驱动策略研究
Research on Dynamic Stepping Drive Strategy for Switched Reluctance Motor Used in Photovoltaic Tracking
摘要
Abstract
Aimed at the problem that the traditional time-controlled photovoltaic tracking system relies on a decelera-tion mechanism and thus leads to efficiency loss and low comprehensive power generation benefit,a dynamic stepping photovoltaic tracking strategy based on the direct drive of a switched reluctance motor is proposed.First,through the analysis of electromagnetic characteristics of a 12/10-pole switched reluctance motor,it is verified that the motor's high starting torque and other characteristics meet the requirements of direct drive.Then,a high-precision anisotropic radia-tion receiving model is adopted,and the stepping angle and time interval parameters of the tracking system are dynami-cally optimized by using an interior point method with a goal of maximizing the system's comprehensive benefit(i.e.,the difference between power generation benefit and tracking energy consumption),and a variable step-size dynamic tracking strategy is put forward.Finally,a photovoltaic tracking system model based on the switched reluctance motor with position-speed-current closed-loop control is established.Simulation and experimental results show that the pro-posed method can effectively reduce the action frequency while ensuring the tracking accuracy.Compared with that un-der the fixed installation strategy,the all-day power generation benefit is improved by 15.5%,and the system's compre-hensive benefit increases by up to 50.1%compared with that under the traditional time-controlled tracking strategy.关键词
