毕节地区小水电发展历史,60年代单站装机容量大都在100千瓦以下,多为孤立运行,发电机端电压400伏直送用户。70年代小水电得到迅速发展,单站容量上升到3200千瓦,大量采用10千伏输电,部分采用35千伏输电,开始形成县级电网。进入80年代小水电单站容量达3600千瓦,初步形成地区级电网并与省网相联,但除各县骨干电站外,大部分小水电仍是将发电机400伏端电压,在电站升压至10千伏输电给用户。经过多年实践和不断
Bijie region history of the development of small hydropower, single station installed capacity in the 60s are mostly below 100 kilowatts, mostly isolated operation, the generator voltage 400V direct users. The rapid development of small hydropower in the 1970s, a single station capacity rose to 3200 kilowatts, a large number of 10 kilovolt transmission, part of the 35 kilovolt transmission, began to form a county-level power grid. In the 1980s, the capacity of a single hydropower station was 3600 kilowatts, initially forming a regional power grid and connecting with the provincial network. However, except for the backbone power stations in the counties, most small hydropower plants still use 400-volt generator voltage and step-up To 10 kV transmission to the user. After years of practice and continuous
