摘要： A yaw auto-calibration method configured to calibrate an anemometer of a yaw control system to correct for yaw misalignment, includes collecting wind speed and wind direction data from the anemometer over a plurality of time periods. The method includes determining from the collected data a wind direction compensation signal associated with a plurality of wind speed ranges. The step of determining a wind direction compensation signal includes determining from a plotted performance value, a maximum performance value for each wind speed range and the step of determining further includes correlating the maximum performance value for each wind speed range with the associated average generator speed and plotting the maximum performance wind direction against average generator speed for each wind speed range. The maximum performance wind direction associated with the average generator speed for each wind speed range constitutes the wind direction compensation signal for the wind speed range.

摘要： A static synchronous compensator includes at least one converter pole for producing a first phase of an AC voltage waveform having a fundamental cycle. The first phase of the AC voltage waveform includes alternating converter pole charging and discharging regions in each fundamental cycle. The at least one converter pole includes a plurality of cascaded H-bridge cells, each having a DC voltage source and a plurality of switches. The switches are capable of being switched to produce a plurality of switching states. There is a controller configured to control the switching states of the plurality of switches of each of the cascaded H-bridge cells based on the voltages of DC voltage sources of the H-bridge cells and on whether the AC waveform is in the converter pole charging region or the converter pole discharging region.
