As a significant part of electrical load, air conditioners draw attentions for their sometimes-unfriendly load characteristics, especially their dynamic responses during grid voltage disturbances. In this paper, a novel under-voltage control strategy for variable-speed air conditioners is introduced, which can keep air conditioners load characteristic as constant impedances when unexpected voltage...
In this paper, a detailed set of reliability prediction methodology for switched reluctance motor drive (SRD) considering system specific control strategy and component fault classification is elaborated from component level to system level. At component level, introduction to SRD and its single switch chopping strategy is presented to capture characteristics of SRD reliability under a certain control...
The proposed Zhairuo Island power system located in Zhoushan, Zhejiang Province, is of capacity more than 5MW. It mainly consists of some marine current energy units, wind turbines, photovoltaic units, and a Li-ion/super-capacitor hybrid energy storage system. This paper reports upon the design of the system, including load balancing scheme, grid electrical design and centralized control strategies,...
