Abstract

Based on proposed state self-adaptive monitor logic and volts per hertz (V/f) control method with current and voltage limitation, a compact operation monitor and control system (OMCS) is developed for real-time monitoring and control of a 6 kV/1600 kVA adjustable-speed drive (ASD) installation. The hardware of OMCS is based on industrial PC and composed of AI and DI data acquisition cards and TMS320C32 DSP based pulse system with specially designed configuration to exempt from strong electromagnetic interference. Implemented under Chinese Window 98 operating system with VC6.0 programming language, the software of OMCS can provide friendly man-machine interface with multi-functions. Experimental results show that the proposed monitor and control system can reliably supervise the operation conditions of ASD and efficiently control acceleration and deceleration of the induction motor without violating limits of current and voltage.
