解釋
柵極控制裝置-
Along with the a enhancing proportion of hydroelectricity in the whole electricity system in our country, the increase of the single unit capacity, the faults ratio of the large - scale hydropower units is more and more important to the whole system safe operation, if we do n ' t manage it well, it will cause the collapse of the whole system and bring a great loss of country ' s economy, hi addition, accompany with " to dispart plant and grid, connect to the grid according to the price " put into practice, how to control the production cost of the power plant has to be put into consideration
隨著我國水電在系統中所佔比重的增加及單機容量的增大，大型水電站和機組的故障率對系統的安全運行也越來越重要，如果處理不好，甚至會引起整個系統的崩潰，給國家帶來巨大的損失。另外，隨著我國「廠網分開，競價上網」的逐步實施，如何控制發電廠的生產成本，也將提上各個電廠的議事日程。 -
Benefited from the ceaseless development of information technology and control technique, research on grid - connected wind power generation has been in fast progress, with commercial application from several kilowatts up to more than one megawatts per unit, and category of controls from stall type to pitch regulation type up to the state - of - the - art varying speed type
隨著計算機與自動控制技術的飛速發展，風力發電技術的發展極為迅速，其單機容量從最初的數十千瓦級發展到最近進入市場的兆瓦級機組；控制方式從基本的定槳距失速型控制向變槳距控制直到最新的變速控制發展。 -
At present, using grid browsers has not been universal yet, so we have to use distributed architecture to simulate the idea of unit control and trusteeship completely in the platform
由於現在網格瀏覽器還不具備通用性，因此計算平臺要實現統一控制和完全託管的思想就只能先由分散式結構模擬。 -
The thesis is a part of the project of developing an electrical control system ( ecs ) for mega - watt scale stall - regulated grid - connected wind turbine generator ( wtg ), which is a key 863 program in the tenth five year plan. at first the thesis introduces the relevant theory of the control system of wind turbine unit, then the framework of ecs and control strategy of mw stall - regulated wtg, as well as the detailed description of function of ecs are put forward. afterward the general design of hardware and software of ecs is presented
本文作為國家「十五」 863子課題?兆瓦級失速型風力發電機組電氣控制系統的研製的一部分，首先介紹了風力發電機組控制系統的相關理論，接著提出了兆瓦級失速型風電機組電控系統的總體結構，進行了有關電控系統基本功能與機組控制策略的設計，在此基礎上，提出了電控系統硬體與軟體的總體實現方案。 -
Today, mw wind generators substitute 600kw generators gradually and become the popular units of international market of wind power generation. the trends of units are variable speed constant frequency and large - scale and pitch control. there are many different generators which are variable speed constant frequency generator. in this paper the unit is fully - fed magnet wind turbine generator. the magnet wind turbine generator grid - connected inverter is the key component of connected system. the main function of this component is inverting the dc to three - level volage and connecting the electric net
實現變速恆頻發電的方法眾多，本文研究的是較常用的一種方案。該方案採用直驅永磁風力發電機通過變頻器直接連接到電網。永磁風力發電機並網逆變器是並網發電系統的核心部分，其主要功能是將經過整流、斬波升壓后的直流電逆變成三相交流電，並送入電網，實現並網。
