The computer aided technology is also known as the EMS/SCADA or SCADA/EMS. When used in this way, the term EMS will exclude the control and monitoring functions but more specifically it will refer to the collective suite of powerful network applications and the generation control as well as scheduling applications. Manufacturers of Energy Management Control Systems commonly supply the corresponding dispatcher training simulator. This particular technology makes use of the components of EMS and SCADA as a training tool for operators in control centers. It is also now possible to acquire an independent DTS like. You can get this from a non-EMS.
The Energy Management Control Systems are typically used by individual commercial centers to measure, monitor and to control their corresponding electrical building loads. Energy management systems can also be used to control devices centrally. You can control lighting systems and HVAC units from across multiple locations like restaurant sites, retail and grocery and control it from a central controlling room. Through energy management systems, you will be provided with metering, sub-metering as well as monitoring functions which allow building managers and facility to gather insight and data which allows them to make informed decisions about energy across different sites.
Operating systems
Up to the 1990s, it was very common to find Energy Management Control Systems delivered based on the operating systems and proprietary hardware. Back then, the suppliers of EMS like Hitacki, Harris Control and Toshiba manufactured their very own proprietary hardware. EMS suppliers which did not manufacture their very own hardware usually relied on the products which were developed by Gould electronics, digital equipment and MODCOMP. EMS models as well as traditional planning models were always maintained independently and seldom found in synchronism with each other. The use of EMS software allows the operators and planners in sharing common model thereby reducing the mismatch which happens between the two. This scheme also cuts the model maintenance by half. If you have a common user interface, this will allow for an easy transition of information from the planning to operations.
As the proprietary systems have become uneconomical, the suppliers of EMS began to deliver the solutions which is based on the industry standard hardware platforms like those from IBM, HP, Digital Equipment and Sun. The operating system which was common was either UNIX or DEC OpenVMS. By the year 2004, there were various EMS suppliers including OSI, Alstom and ABB had begun to offer solutions which were Windows based. During 2006, customers were given the choice of Linux, UNIX or window based systems. There were some suppliers that continue to offer the UNIX based solutions.
