介绍了直流电增能技术的基本原理、先进性和经济性。叙述了最新研发的虚拟六相整流器, 通过检测表明, 增能增效潜力十分明显, 而且实测效率高于三相桥式整流器。随着智能电网、微电网的兴起, 特高压直流输电的启运, 原先受直流电网发电机转速和频率约束的屏障, 有可能被交流电增能技术突破, 从而进一步提高电能转化效率和提升设备运转效益。也就是说, 不管是燃煤发电、水能发电、核能发电还是风能发电, 都可以采用交流增能技术或者直流增能技术的不同相关技术, 结合现有的发电、变电、输电先进技术产品, 来提高电力系统的输出功率和发输电效率。

The set of 3 papers introducing the Power Increment Technology (PIT) which inclosing DC Power Increment Technology, AC Power Increment, and their foundation principle, advantages and economic development, will be published in installments by the journal.The first installment here will have an introduction about our PIT, and first of all discloses our Virtual Six-phase Rectifier listed among DC Power Increment Technology.The test shows that a potentiality of VSR among increments of power and increments of efficiency, it is shown obviously that the VSR is more efficient than that of the common three-phase bridge rectifier.Upon the excitement of the smart powergrid technology, microgrid technology, especially the( ultra) high voltage DC power transportation, the limitation in the speed and frequency of a generator caused by the synchronous grid might be brocken by AC Power Increment Technology, then the increment of power conversion efficiency and the reduction of equipment cost are expected.And that means whole the coal power plants, hydro power plants, nuclear power plants and wind power plants can increase their power output, increase their power generation efficiency and power transportation efficiency, meanwhile their equipment capital can be reduced, if the technology of DC Power Increment and AC Power Increment are applied, and if other advanced technology of present manufactures are combined with.
