摘要
针对电机驱动功率超过350 k W的海工电动绞车,设计绞车变频调速电气控制系统,服务于半潜式海洋平台上,具备起抛锚和平台移动等控制功能。根据绞车调速性能要求高、驱动功率大的特点,对变频器、制动电阻等主要元件进行选型计算,设计控制流程。现场调试使用表明,系统满足调速性能及控制要求。
A variable-frequency electric control system was designed for the winch with over 350 k W motor drive power,which serves the semi-submersible offshore platform and has the control functions of anchoring and platform moving. According to the characteristics of high speed performance and high driving power,the main components such as frequency converter and braking resistor were selected and calculated,and the control flow was designed. Practical application showed that the system meets the speed control performance and control requirements.
