Fault Analysis And Protection Of Multi Terminal Mmc-Hvdc Oh Transmission Lines For Wind Farms Collection Grid
The wind power industry today is exceptionally intrigued by arrangements that will bring down the expense of energy without bargaining the specialized exhibition of wind power plants to guarantee that wind power stays serious. In journey of high proficiency, power thickness and issues of mass force transmission over significant distance, necessity of full command over power transmission and developing revenue to fuse environmentally friendly power source into the grid has prompted build up another time of high voltage direct current (HVDC) transmission system. The interconnected voltage-source converter based multi-terminal high voltage DC systems system redundancy, higher flexibility and capability of exchanging power between multiple areas. Multi-terminal direct current grids give the chance of coincided interconnections between provincial force systems and different sustainable power assets to support supply dependability and economy. The modular multilevel converter (MMC) has become the essential structure block for MTDC and DC grids because of its remarkable highlights, i.e., modularity and adaptability. Accordingly, the MMC-based MTDC systems ought to be inescapably inserted into the current force system to improve system execution for wind structures gathering grids. Be that as it may, a few specialized difficulties hamper their viable applications and sending, including demonstrating, control, and protection of the modular multilevel converter - Multi-terminal direct current grids.
