广东省惠阳地区至1985年止,已建成小水电装机15万千瓦。由于1982年以前,受当时条件及电网布局的限制,有相当大部分水电站的变压器是采用配电变压器(10/0.4KV)。并入省电网后,给小水电站的运行带来一些不良后果:一是无功发不足,供电质量差,造成一定的经济损失,影响了小水电的威信。根据博罗县显岗水库等8个站的统计,1983年实发有功1270万度,实发无功708万度,无功仅占有功55.7％,欠发无功241.25万度,被扣款57108元,占
The Huiyang area of Guangdong Province was completed in 1985, with 150,000 kilowatts of small hydropower installed. Before 1982, due to the constraints of prevailing conditions and grid layout, a large part of the transformers of hydropower stations were distributed transformers (10/0.4KV). After being merged into the provincial power grid, the operation of the small hydropower station has some negative consequences: First, the lack of reactive power, poor quality of power supply, resulting in certain economic losses, affecting the prestige of small hydropower. According to the statistics of 8 stations including Xiangang Reservoir in Boluo County, in 1983, there were 12.7 million kWh of active power, 7.08 million kWh of reactive power, and 55.7% of reactive power, and 2.225 million kW of reactive power was deducted. 57,108 yuan, accounting for
