1. Project goals and objectives This project aimed at developing analytical models and methods for assessing the seismic response of electrical substation equipment connected by assemblies of rigid bus (RB) and flexible strap connectors (FSC) or slider connectors (SC). Also developed is a method to estimate the reliability of electrical substation systems subjected to stochastic earthquake load...

With the development of substation automation technology, unmanned substation operation mode has become a trend, at present, many substations to achieve the "remote viewing" function, will be the scene of the substation, the equipment state to video image transmission to the remote control center (set control station). And scheduling center (set control station) on live video equipment to contr...

Embedded Generation (EG) is a small scale production of power, typically located close to electricity consumers. Technologies used for EG include combined head and power, solar, wind, biomass, and gas. In Ontario, as a result of the Standard Offer Program (SOP), a large amount of EG projects has been proposed to be directly connected to distribution systems in the IESOControlled Grid (ICG). The...
