In power distribution network, resistor is commonly series with the passive filter in order to avoid its resonance with line impedance. A power electronics converter based Active Harmonic Resister (AHR) is proposed in the paper to replace the passive resistor. With the proposed method, potential resonance could be efficiently suppressed, and the active power loss in passive resistor is gone. The proposed...
This paper presents the enhancement of voltage sags, harmonic distortion and low power factor using Distribution Static Compensator (D-STATCOM) with LCL Passive Filter in distribution system. The model is based on the Voltage Source Converter (VSC) principle. The D-STATCOM injects a current into the system to mitigate the voltage sags. LCL Passive Filter was then added to D-STATCOM to improve harmonic...
It is an effective measure to reduce voltage distortion and guarantee power quality by allocating active filters in distribute network. The location and parameter of active filters are coded firstly, then the active filter's capacity is calculated through solution variable based on calculation of the harmonic power flow. This ensures the filter's safty operation constraint. The current optimal variables...
In this paper, a Z-source hybrid active power filter is proposed to compensate the harmonics and reactive power in power distribution system. The proposed system is composed of a 7 th harmonics-tuned passive filter and an active power filter with a Z-source inverter topology, while voltage source PWM inverter or current source PWM inverter are applied as the power converter topology of conventional...
The widespread application of power electronics is introducing non-linear loads in the distribution system resulting in the distortion of current and voltage waveforms. In this paper, IEEE 13-bus distribution system is considered for analysis of harmonics. The distribution system model is simulated in PSCAD/EMTDC software with static and adjustable speed drives as loads. Harmonic analysis of the system...
The harmonic distortion of voltage has became an important subject in power quality, especially after use of power electronic equipment and nonlinear loads. Simple method to limitation of harmonic distortion is using of passive filters. The objective of this paper is to determine the location and size of passive filters in distribution networks economically, by using genetic algorithm. With using...
