Harmonic Filtering

Nowadays, the use of power converters to control active and reactive power in AC–AC grid-connected systems has increased. With respect to indirect AC–AC converters, the tendency is to enable the back-to-back (BTB) voltage source converter (VSC) as an active power filter (APF) to compensate current harmonics. Most of the reported works use the BTB-VSC as an auxiliary topology that, combined with other topologies, is capable of active power regulation, reactive power compensation and current harmonic filtering. With the analysis presented in this work, the framework of the dynamics associated with the control loops is established and it is demonstrated that BTB-VSC can perform the three tasks for which, in the reviewed literature, at least two different topologies are reported. The proposed analysis works to support the performance criteria of the BTB-VSC when it executes the three control actions simultaneously and the total current harmonic distortion is reduced from 27.21% to 6.16% with the selected control strategy.

Simulation Results

Passive power filter (PF) has problems that source impedance may strongly affect the filtering characteristics and cause system resonance in power system applications. Hybrid active power filter (HAPF) can improve the performance of passive filter and realize harmonics restraint and reactive power compensation in big power situation. In this paper, the principle of HAPF is analyzed, the model of HAPF is established, and the simulation results are discussed.

Wind Power System

As a new dynamic reactive compensation devices, static synchronous compensator (STATCOM) has better reactive power compensation effect such as small in size, capacity, continuous adjusting, fast response and economic performance compared with SVC. It is suitable to be used in large-scale wind farm to improve the voltage stability of wind power system. With the help of ideas and methods in conventional electric power system to calculate the two-dimensional parameter bifurcation boundary, the node voltage two-dimensional saddle-node bifurcation boundary of wind power system was calculated by using wind farm active power inject(Pin ),STATCOM parameters KMdc and Vrefdc as bifurcation control parameters. And on the basis of this analysis, the laws of wind power system voltage stability affected by active power and STATCOM parameters were obtained.
