Abstract EN

In recent years with the excessive consumption of electrical energy, the incongruity between generation and demand, the irrational structure of World’s energy as well as the environmental pollution have become progressively more evident.

It has become crucial for ecological development to reduce the consumption of conventional energy and to enhance the development and utilization of renewable energy.

Wind energy and Solar are unlimited supply of renewable energy and it has no pollution.

But this concept suffer from the power quality issues from grid and generator side, this paper presents a control strategy for achieving maximum benefits from these grid-interfacing inverter when installed in 3-phase 4-wire distribution systems.

The inverter can be controlled to perform as a multi-function device by incorporating active power filter functionality.

The inverter can thus be utilized as: 1) power converter to inject power generated from RES to the grid and 2) shunt APF (Active Power Filter) to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current.

All of these functions may be accomplished either individually or simultaneously.

With such a control, the combination of grid-interfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at point of common coupling appears as balanced linear load to the grid.

The Paper propose design of 500kW Type I Wind Generation System 250kW each with Four Leg Inverter Controlled by d-q technique operated as DSTATCOM connected to 415V 4 wire Grid and also the results are compared with conventional Unit Vector Control.

The proposed d-q method reduces the %THD of system to 1.97 % from 24.12 % where Unit Vector Control is of 3.94 % which was on higher side , this is simulated in MATLAB/SIMULINK.
