And dc speed control system wide speed range, static, good stability and small rate differential with good dynamic performance, high performance in the drag technology areas, a quite long period of almost all adopts dc electric drive system. Double closed loop dc speed control system of dc motor control system is the most mature development, are widely used in power transmission system. Dc double closed loop speed regulation system performance is good, has wide speed range, high accuracy, good dynamic performance and easy to control etc, and so in electrical transmission system in a wide range of applications. Dc double closed loop speed regulation system set up two regulator, namely the speed regulator (ASR) and current regulator (ACR), speed, regulate and current. In this paper, the dc double closed loop speed regulation system design based on the analysis of the dc double closed loop speed regulation system of the principle that the current regulator introduced some speed regulator and the design and some parameter selection and calculation, make its meet the engineering design parameter index. From the principles of dc machines work, set up double closed loop dc speed control system, and the mathematical model of a detailed analysis of the system, the principle and the static performance. This paper expounds is the speed, current double closed loop dc speed control system single closed loop dc speed control system retold the circuit design and research. Main circuit design is based on thyristormotor (VM) system position, the system by the rectifier transformer TR, thyristor rectifier control device, flat wave reactor L and motorgenerator etc. Rectifier transformer TR and grain brake canal rectifier control device is the function of the input ac after rectifying into d。 Flat wave reactor is the function of L output of the dc current smooth。 Motorgenerator for threephase ac power. 4 目錄 摘要 ................................................................................................................................................. 2 ABSTRACT .................................................................................................................................... 3 1 前言 .............................................................................................................................................. 5 課題背景 ........................................................................................................................... 5 課題現(xiàn)狀 ........................................................................................................................... 5 課題研究內容 ................................................................................................................... 5 2 串極 調速系統(tǒng) ............................................................................................................................. 6 主電路方案的確定 ........................................................................................................... 6 系統(tǒng)靜態(tài)及動態(tài)要求 ....................................................................................................... 6 串極 調速原理及基本類型 ............................................................................................... 7 電動機供電方案的確定 ................................................................................................... 9 3 電動機容量校核 ........................................................................................................................ 11 最大轉差率 ..................................................................................................................... 11 轉子整流器的最大輸出電壓 ......................................................................................... 11 最大直流整流電流 ......................................................................................................... 12 最大直流整流電阻 ......................................................................................................... 12 定子電阻 ......................................................................................................................... 12 電動機額定轉矩 ............................................................................................................. 13 4 硬件元件的選擇 ........................................................................................................................ 14 整流二極管的選擇 ......................................................................................................... 14 整流二極
