The unified power quality conditioner (UPQC) has become one of the most proficient solutions for compensating effects voltage fluctuations, harmonics, sudden load changes and enhancing distribution networks. Aiming at shortcomings conventional compensation control strategies effect UPQC, this paper proposes an effective strategy UPQC based on dq0 detection method. Furthermore, space vector pulse width modulation (SVPWM) algorithm is improved in paper. fundamental harmonic supply side current...
In this paper, a novel model predictive control (MPC) via double vector optimized selection method is proposed. The main idea of for decreasing the high common-mode voltage two-level inverter under balance situation, improve tracking performance output current and decrease harmonic distortion rate. To solve problem increasing value total (THD) due to reduction available vector, controls two vectors in each sampling period getting better current. Simultaneously, compared with adding virtual...
In operation process of ultra supercritical unit, the stability superheated steam temperature depends on adjusting fuel water ratio correctly. order to improve speed and accuracy ratio, in this paper active disturbance rejection control technology was used system units, proposing that secondary system, main regulator ADRC, traditional PID control, that's design ADRC-PID system. The can within permitted changes, eliminate various disturbances rapidly finely, adjust outlet spray...
When the grid is under condition of unbalanced voltage, problems such as inverter output active and reactive power oscillation, quality degradation overcurrent can be occurred. In order to overcome these problems, there are three different controlling targets: balancing current, suppressing well fluctuation. According instantaneous theory, it impossible achieve all targets simultaneously. This paper proposed a grid-connected current quality/power coordinated strategy. The method which uses...
Abstract The electromagnetic transient simulation of large-scale MMC has the problems large memory requirements and long time, which restricts development research [1-3]. To solve problem low efficiency simulation, this paper proposes a fast energy equivalent model for MMC. Thus, under normal working conditions can be realized. First all, rationality achieving Norton bridge arms is derived from node voltage analysis method. Then modeling method controlled source obtained. On basis, that...
