The Hitachi Energy Intelligent Electronic Devices (IEDs) for protection and control are an integral part of the substation automation system. Combined together, the SAS and IEDs lay the foundation for all higher-level remote functions such as advanced power system management and monitoring of equipment condition while in service. Station level systems are easy to use and adapt to customer-specific requirements.
Increasing competition is driving many power providers to focus on system productivity, with a view to reducing costs and increasing customer satisfaction, which often involves upgrading the aging infrastructure.
Older protection and control systems can be easily upgraded using Hitachi Energy's modular systems. Updating substation automation offers the opportunity to reduce operational and maintenance costs, increasing plant productivity with the aid of enhanced schemes as well as condition monitoring for circuit breakers, power transformers, etc.
