ระบบจัดการพลังงานในโรงงานอุตสาหกรรม (Factory Energy Management System: FEMS)It is the most complex energy management system of the future, as it controls production and energy consumption within a factory, and each factory's electrical energy usage varies depending on its specific production processes. While BEMS or HEMS are limited to controlling specific electrical systems or devices such as HVAC, heating systems, or lighting, FEMS must work in conjunction with the existing factory control systems, and may also need the capability to manage machinery schedules and equipment maintenance, among other tasks.Designing a FEMS is significantly more complex due to the need for a detailed understanding of a factory's energy consumption behavior, including in-depth knowledge of its production processes. Nevertheless, FEMS offers substantial benefits to the industrial sector, as it can enhance energy management capabilities and support compliance with the ISO 50001:2011 standard for Energy Management Systems. This standardizes energy management practices.In general, FEMS may collaborate with various non-energy-related systems, such as Quality Control, Safety Management, and Environmental Management systems. FEMS should possess the capability to seamlessly integrate with these systems and contribute to the overall development of the industrial facility, ultimately transforming it into a Smart Factory.
In addition, Factory Energy Management System (FEMS) also includes services for energy management in industrial plants. It comprises an electricity consumption tracking system, machinery operation management including equipment maintenance, control systems to enhance the efficiency of in-house energy production, energy storage systems, load responsiveness control, heating and HVAC control, lighting control, and data collection and processing from smart meters, among others.
