10% to 15%. According to relevant public information, the proportion of conversion cabinets varies according to different wind power systems. Generally speaking, this is a relatively normal range that represents 10-15% of the total wind system investment. The wind turbine system conversion cabinet is one of the main devices that converts the alternating current generated by the wind turbine into direct current and converts the direct current into alternating current required by the power grid.
Generally speaking, this is necessary for the production of photovoltaic energy, taking solar power plants as an example. Solar cells emit direct current and the grid power supply is usually alternating current, so a converter is required. to convert direct current into network. The communication required; and in the early days of wind power development, there were wind turbinessmall-power generators that could directly connect electricity generated by wind speed to the grid without going through it. a converter. However, with the development of technology, in order to achieve more For large-scale wind power generation, the currently widely used dual-feed units and direct drive units use converters to convert the generated energy into energy electrical meeting the requirements. network access conditions. Therefore, currently, technically it is necessary to connect to the network via a Mainstream converter!
