Circulating current can be decomposed into double line-frequency positive-, negative- and zero-sequence components under unbalanced voltage conditions. First, in order to decrease peak/rms value of arm current, double line-frequency circulating current should be eliminated. Second, ac-side current that consists of positive- and negative-sequence components under unbalanced voltage conditions should...
Voltage sag or instant power loss often happens in power supply system in the thermal power plant. Aiming at settling the problem of the serious power plant accidents that the low voltage protection of the inverter is blocked, boiler main fuel is tripped, auxiliary equipment is stopped, and the generator units is non-planed acted by voltage instability, the inverter low voltage ride through power(ILP)...
Due to the energy crisis and global warming problems, most of the countries place more and more emphasis on the development of distributed generation (DG) using renewable energy. In China the installed capacity of distributed generators is rising, from isolated micro-grid system to grid connected system. With the increasing penetration of distributed generation, especially for the converter interfaced...
