Con Edison has entered into a demonstration project with EPRI, a Con Edison customer, and a Con Edison facility to evaluate different technologies for energy storage and other power quality mitigation techniques. The focus of this project was to select, test, and install a power conditioning device that would provide voltage sag ride-through for Con Edison customers. The Roesel written-pole motor generator (RMG) was selected as a result of the initial phase of the project. The RMG is a relatively new type of electrical device that can offer many of these needs in one package. The RMG can compensate for transients, and voltage variations and regulation in customer facilities. This application guide is designed as a resource for engineers to better understand the RMGs as customer end-use power quality solutions. The guide explains the basic operation of the RMG and how they compensate for voltage variations on the power system. Common power quality problems are also discussed, test results from two demonstration projects are presented, and information is given for determining the applications for the use of RMGs. A description of EPRI`s and Con Edison`s experience with a three, 35 kVA RMG installation in Manhattan and a single, 35 kVA RMG installation at a Westchester location is included. These case studies were designed to demonstrate the power quality impact of an actual RMG in the field. Important practical considerations such as the RMGs ability to regulate the output voltage during variations on the input are discussed. Also, installation concerns are addressed in the design guide. The process by which the RMG was selected as a power quality solution is also explained. This includes a discussion on pre- and post-installation power quality audits and how to compare the results of this examination against the capabilities of the RMG.
