Recently, the country's first real-time monitoring and assessment of wind energy systems research and development in the Northwest Power Grid Corporation completed and successfully put into use, to achieve a daily 5 to Jiuquan wind power wind power provided 96 points and wind farm output prediction analysis service for new developed and distributed energy focus on intelligent line access equipment monitoring, mitigation 10 million kilowatts of wind power base of the grid after the impact of access, to solve large-scale wind power development in Northwest Region, and network with other issues to run a strong technical support.
The system consists of the regional Northwest Power Grid (Jiuquan,) wind measurement network and wind power scheduling real-time monitoring system of two parts. Northwest Power Regional (Jiuquan) wind measurement network scheduling is the first for the regional power grid scheduling wind wind power network into operation in early 2010, can be realized, including 10 meters, 30 meters, 50 meters high and 70 meters height of two 5 channels of the wind resource data in real-time acquisition, transmission; wind energy real-time monitoring system was recently put into use, generate real-time monitoring of the region's wind energy resource map of wind power to predict and calculate the theoretical output of all wind farms .
The system uses a multi-sensor fusion, pattern recognition, three-dimensional simulation and other advanced intelligent technologies, wind power base in the region according to climatic features and topography, surface roughness conditions, linear analytical method used to establish a wind energy evaluation model, to the wind conditions scientific assessment of wind farm output; based geographic information system, using hierarchical distributed architecture, to realize the wind speed, wind direction, temperature, pressure and other information, real-time monitoring, for 4-6 hours of short-term nowcasting, to revise recently forecast bias, and comprehensively improve the forecasting of wind power, to effectively alleviate the impact of wind power on the grid, for the five northwestern provinces (districts) networking, and web Beijing Xin Neng Yuan under large-scale network security and stability Yunxingtigong Jishu protection.
