Conventional three-phase rectifiers are controlled to achieve good power factor and low total harmonic distortion in the input. In the case of pulsating power loads, the fast dynamic response implies that the load pulses are reflected in the generator. These pulsating loads affect the lifetime operation of the generator, especially when it is not oversized (as in the case of aircraft applications)...
This paper presents the characteristics analysis of wind farm to the participation of power grid frequency regulation. Wind farm is built by equivalent modeling method, and contains full-converter wind turbine generators (WTG) with Wind Turbine of Direct-Drive Permanent Magnet Synchronous Generator (DDPMSG). At first, model and control strategy of WTG with PMSG is introduced. Then single-machine equivalent...
Steam Generator (SG) is a major component in a nuclear power plant. Poor control of a nuclear steam generator can lead to frequent reactor shutdowns or it can damage turbine blades. To avoid such costly reactor shutdowns, there is a need to systematically investigate the problem of controlling the water level in the steam generator. In this work, we have proposed a novel concept of feedback-feedforward...
The simulations of pressurized water reactor (PWR) nuclear power plant (NPP) is a very important domain in the society of nuclear power, and there are several problems with the current PWR-NPP simulations. First, the current physical modeling of PWR is over-simplified which can bring convenience of implementation, while severe inaccuracy is prone to be incurred at some critical situation. Second,...
