摘要

A constant power control system based on Serial communication between a programmable logical controller (PLC) and a converter is put forward for high efficiency of oilfield workover rigs and for simple operation and reliability. In the condition of different transformers' capacity, this system makes the motor always be in constant power state automatically by selecting power limit values. Operators with different practices can make use of this system because of its manual function which meets the demand of humanized design. This system can be used in other lifting equipment whose operation mode is similar to workover rigs.
