改變速度模式-
In this paper, several scheme of vscf is compared firstly, of which gets doubly - fed generating mode. doubly - fed vscf wind power generating system uses a doubly - fed induction generator, which rotate speed can be able to change with wind turbine, and it ensures a constant - frequency output, by controlling the frequency of current input into rotor windings. in vector trans control system, the control of stator active power and the control of stator reactive power can be essentially decoupled, and the former is via torque component and the latter is via exciting component of stator current
本文首先比較了幾種變速恆頻方案，從中選擇了雙饋式變速恆頻方案；它運用雙饋電機的工作原理，允許發電機轉速變化，而在電機轉子側接入低頻勵磁電流，通過控制該電流的頻率，保證雙饋電機定子輸出的頻率恆定；再結合矢量控制技術，通過調節轉子電流來控制定子電流的轉矩分量和勵磁分量，相應獨立地控制發電機輸出的有功功率和無功功率。 -

The system abandons the serial communication that is low speed and low effect, but change to use the printing port, realizes the high speed, efficient parallel communication, further more choose to use to the ecp ( extended capabilities port, ) mode of parallel communication. according to the outside physical transfer ability, this mode can automatic adjust the transfer speed, and realize the data communication with the arbitrary speed
該系統在上下位機的數據傳輸中，摒棄了低速、低效的串列通訊，而改用列印口，實現了高速、高效的并行通訊，並且選用了並口的ecp （ extendedcapabilitiesport ，擴展功能介面）模式，可以根據外設的實際傳輸能力自動調整傳輸速度，實現任意速度的數據通訊。 -
Along with the advancement of technology, human are changing all aspects of environment at unprecedented speed the change of the utilizing land resource make the style of utilizing land resource change with each passing day for the land manager, as the traditional mode of manage can not adapt the change of utilizing land resource, they need a sort of land resource management information system which can update graph and data at real timeo the appearance and development of " 3s " ( remote sensing globe position system geography information system ) technology improve the change from traditional map to digital map, and offer the platform on which the land resource management information system can be developed which can satisfy the manager ' s requirement, and make it possible that develop the land resource management information system by the manner of system integration the article set forth the method and technology of developing the land resource management information system from the aspects of the manner of development the instruments of integrated development the design of system the data ' s organization the technology of integrated development
隨著科學技術進步的速度越來越快，人類正以空前的速度改變著自然環境及其各個方面，人類對土地資源的利用也發生著日新月異的變化，使得土地資源的利用類型隨時隨地發生改變，對于土地管理者來說，傳統的管理模式已經不能夠適應當前土地利用的變化速度，急需一種能夠實時更新圖形和數據的土地資源管理信息系統。 「 3s 」 （遙感技術、全球定位系統、地理信息系統）技術的出現和發展，推動了傳統地圖向動態的數字化現代地圖的變革，為建立滿足當代土地管理者需求的土地資源管理信息系統提供了可能的平臺，使得採用系統集成方式進行土地資源管理信息系統開發成為可能。本文主要從開發方式的選擇、集成開發工具、系統設計、數據組織、集成開發技術等五個方面闡述開發土地資源管理信息系統的方法及相關技術。
