Application of mobile agent technologies for power control of distributed generations in an isolated microgrid is proposed to address future flexibility and economic requirements. A conventional generator, a battery energy storage system, and a fuel cell are considered as distributed generation systems in an isolated microgrid. Reasonable operation of the microgrid was achieved using the proposed...
As mechanical vibration usually exists in HV motors and generators, its influence on the partial discharge (PD) needs to be studied so as to improve the reliability of on-line PD monitoring method. In this report, the mechanical vibration frequency was synchronized to the power frequency and the effects of vibration phase and frequency were investigated. Because the length of the discharge gap changed...

Summary form only given. Surge tests were performed to derive a generator model considering its frequency characteristics. Impulse voltages were applied to one terminal of the generators after placing a variable capacitor at the same terminal. The inductances and the core-loss resistances of a generator model can be determined from the measured oscillating voltages. This paper presents a generalization...
