Abstract :
Dynamic Power Limited (DPL) is a 50/50 joint venture between Rolls-Royce and Scottish Power. The Company provides a range of power quality enhancement systems, known collectively as “Custom Power”. These systems, based on technology developed by Westinghouse, are designed to protect users from disruptions to their operations which result from power supply disturbances. A Custom Power device provides “wide area” power quality protection: that is to say a single device can protect all of a plant´s critical loads, rather than protecting a single load like a UPS product. The Custom Power products are appropriate for large energy users which are particularly sensitive to the quality of electricity supply (e.g. chemical manufacturers, paper mills, semiconductor factories, automotive factories) and to the electric utilities supplying these users. The processes employed by these industries are becoming increasingly sophisticated and in many instances this has resulted in plants becoming more susceptible to production losses resulting from imperfections in supply quality. Although the UK enjoys very high levels of power quality, a typical industrial user might experience between 10 and 50 power quality-related disturbances in a year. No utility can guarantee that its supply will be free of such disturbances since they are caused by events outside its control
