This paper proposes a flexible neutral grounding method based on electromagnetic hybrid Petersen coil (EHPC), which consists of a magnetically controlled reactor and an active power compensator (APC). Under normal conditions, the system's neutral point grounds through a reactor of high reactance. When a single line-to-earth fault occurs, the EHPC can be controlled flexibly to suppress the recovery...
The base of operating magnetic-valve controllable reactor (MCR) is the power electronics device which can create steady pulses. In this paper, a model of MCR is introduced and a novel control device for the MCR is proposed, this device uses a special circuit to get a synchro signal from line-to-line voltage first, and then divided into six controllable trigger pulses precisely, the method can be implemented...
Accurate and swift control is the base of operating magnetic-valve controllable reactor (MCR). In this paper, a novel control method for the MCR is proposed, this method uses a flexible algorithm to get a synchro signal from line-to-line voltage by special signal process first, and then divides the synchro signal into six controllable trigger pulses precisely, operate the MCR according to associated...
This paper evaluates immune genetic algorithms (IGA) as a new nonlinear technique for control of inverter. The so-called IGA strategy is characterized by its speediness, diversity, tolerance and memory. It is well suited for online microprocessor implementation. A special C program for the algorithm is compiled. And the dynamic experimental platform based on DSP was built. Simulation and experiment...
