小水电站发电机起励自动并网系统

由于全国电力供应紧张，上网电价上扬，农网改造的完成及电力体制改革的深入，使得小水电上网变得即方便又有较好的经济效益。但一些小水电站因建站时间已久，发电机的起励、并网系统较落后，操作也不方便，已不适应上网要求。为此，我们设计了一套简洁、实用、价廉的半自动系统，满足了发电机的起励，并网及励磁的要求。

The Generator Electromagnetism Excitation and the Power Grid Access System for Small Water Power Stations

Because national electricity supply is in shortage,the power grid access make electricity price rise,the agriculture power grid reforms have been completed and the electrical power system reforms thorough,the small water power stations' grid access becomes more convenient and its performance becomes better.But some small water power stations have been built for a long time,the generator electromagnetism excitation and power grid access system has fallen behind,the operation is inconvenient too,which can not fulfill the request of electrical net access.For this,we designed a equipment which is a simple,practical and cheap semi-automatic system to solve the problems of generator electromagnetism excitation and the electrical net access.The actual using effect is good.
