Automation And Control Volume 1 Design Requirements

Introduction:  This manual gives a brief description of state-of-the-art technologies used to develop high efficiency motors, including premium efficiency induction motors, permanent magnet motors, and switched reluctance motors. It also analyses issues that affect motor system efficiency and provides guidelines on how to deal with those issues namely by:  Selection of energy‐efficient motors  Properly sizing of motors;  Using Variable Speed Drives (VSDs), where appropriate. The use of VSDs can lead to better process control, less wear in the mechanical equipment, less acoustical noise, and significant energy savings;  Optimisation of the complete system, including, the distribution network, power quality and efficient transmissions;  Motor Systems Energy Assessments  Taking Measurements  Applying best maintenance practices.  Motor Repair  How to win approval for energy efficiency projects  Energy Management Systems

Introduction: Design calculations establish minimum guidelines and requirements for generating electrical calculations on projects. Electrical calculations should be made for all SPU projects that include electrical components and should be filed in the project notebook. Design calculations may be made either manually or by SPU-approved computer programs
