Improving Process Control Immunity to Supply Voltage Sags in Petroleum and Chemical Industries
MetadataShow full item record
In the modern industrial facility, many electrical and electronic control devices are routinely integrated into automated processes to increase both energy efficiency and productivity. In many cases these controls turn out to be very sensitive to power quality variations. In fact, they can be just as sensitive to minor power system voltage sags as they are to complete power failures. The end result being that the process experiences a costly interruption in production or output. This paper is a supporting document to the paper "Voltage Sag Related Upsets of Industrial Process Control in Petroleum and Chemical Industries." Both documents describe industrial process sag and interruption related problems and solutions. In particular, this paper focuses on the range of solutions that may be implemented to resolve common power quality related upset problems with large process applications.
