Power Quality is an essential aspect for reliable operation of power grid, including inverter based wind power generation. This paper focuses on real time problem harmonic injection and resonance in power network for 5MW Wind Power Plant. The Wind Plant includes 10 inverters, each of 500KW and connected to 33KV bus. Wind Power is evacuated at 220 KV Substation via 4 km Cable of 33 KV. At certain wind...
Common-mode current generated by the pulse-width modulated (PWM) ac drive at low modulation index and higher switching frequency results in overheating of the precharge resistor of the silicon-controlled rectifier (SCR)-based rectifier. In this paper, two modifications are proposed for the operation of SCR-based rectifiers to significantly reduce the resistor overheating issue. The solution is cost...
Common-mode current generated by the PWM AC drive at low modulation index and higher switching frequency results in overheating of the pre-charge resistor of the SCR based rectifier. In this paper, two modifications are proposed for the operation of SCR based rectifiers to significantly reduce the resistor overheating issue. The solution is cost and size effective when compared with alternative solutions...
More utility companies now require wind power plants to participate in grid support functions including frequency, voltage and inertia support. Typical wind turbine generator configurations cannot provide grid support. In this paper, a multi-level inverter based wind turbine power conversion system is investigated. The developed inverter interfaces between the DC bus of a wind turbine power conversion...
