光伏直驱变频离心机中发电与耗电实验研究

The Power Generation & Consumption Experiment of PV Directly Driving Variable Frequency Centrifugal Chiller

光伏直驱变频离心机的最大特点是直接利用太阳能的直流电,通过直驱方式可减少DC/DC、DC/AC转换的损耗,提高能源利用率。本文通过对光伏组件的发电特性和光伏直驱变频离心机的耗电特点进行研究,提出两种控制方法,保证最大限度的利用太阳能,提高太阳能直驱利用率。

Directly use the solar energy by direct current is the biggest feature of PV Directly Driving Variable Frequency Centrifugal Chiller. This mode can reduce the conversion loss of DC / DC,DC / AC converter,improve the energy utilization. By researching the characteristic of PV power generation and power consumption of PV Directly Driving Variable Frequency Centrifugal Chiller,this paper proposes two kinds of control method which can maximize the use of solar energy and improve the solar direct utilization rate.
