太阳能做为世界上最清洁的能源,目前有着广泛的用途。但由于质量、价格的限制,太阳能发电在国内的利用还处在低水平上,与中国的经济发展形成很大的反差。随着人民生产水平的提高,解决偏远地区居民用电问题也摆上了政府的议事日程;同时各类无人值守地点也适合太阳能发电系统,如各类微波传送站、无线发射点、水文监测点等,随着国家对环保要求不断高,对太阳能发电的需求越来越多,因此迫切需要一些价廉物美的太阳能发电系统。-Solar energy as the world' s clean energy, curr

随着电力系统的发展,电网的容量,电压等级不断提高,大型高压变压器作为电能传送的枢纽,它的安全运行与否,直接关系到电力系统能否连续稳定地工作。特别是由于大型变压器结构复杂、造价昂贵,一旦发生严重故障而损坏,将给维修工作带来很大困难,造成经济上的重大损失。微机继电保护系统作为一种能反映电力系统故障和不正常状态、及时动作于断路器跳闸或发出信号的自动化设备能自动、迅速和有选择地切除故障组件,使系统免遭损坏。因此对于研制开发性能优良的变压器微机保护装置具有十分重要的现实意义。
