一种在瞬间内可使小型水电站与电网自动实现同步运行的并网技术(自同期方式),最近由水电部水电规划设计院和湖北省科委主持下,在湖北通城县试验现场通过技术鉴定.目前我国的小型水电站不少已并入地方小电网,有的还并入国家电网运行.但并网一般还是沿用手工操作的“准同期”方式,并网时间长,往往需要十几分钟到一两小时.若采用自动化的“自同期”并网,一般在三十秒钟内就能使小电站并网运行,迅速维持电网平衡,减少调度环节,防止弃水,利 A kind of grid interconnection technology (self-synchronism mode) that can make the small hydropower station and power grid automatically run synchronously in an instant, under the auspices of the Hydropower Planning and Design Institute of the Ministry of Water Resources and Hubei Province Science and Technology Commission recently, at the test site of Tongcheng County, Hubei Province, At present, many small hydropower stations in our country have been incorporated into small local power grids and some have also been integrated into the operation of the national power grids. However, grid interconnection is generally followed by hand-operated “quasi-contemporaneous” methods. Grid connection takes a long time and often takes ten minutes To an hour or two.If the use of automated “from the same period” and the grid, it is generally within thirty seconds to enable small power plant operation and quickly maintain the power grid balance, reduce scheduling, to prevent waste water
