Industrial Energy Management System (iEMS) based on LonWorks Technology

Energy conservation is one area of present national focus due to limited energy resources, acute power shortage, and the ever-widening demand-supply gap. Studies conducted by various national and international agencies indicate that in industries, energy savings of 5% to 10% can be obtained by simple monitoring and an additional 10% to 15% can be achieved by monitoring and control. As most of the industries feel the pinch of increasing energy costs day by day, they are looking for conservation and better utilization of energy.  An effective, reliable, and robust energy monitoring system is a prerequisite for achieving sustained energy efficiency. This provides a quantifiable scientific base for continuous monitoring aids in evolving a goal and ultimately facilitates achievement of lower levels of energy consumption through automatic control with interlocking facilities.

• The Energy Management System (EMS) acquires data from different energy-consuming areas in various sections of the plant and logs the information and generates reports.
• This information can be used for taking appropriate action by generating control signals leading to improvement in energy efficiency.
• Based on the ‘online’ measured data and the manually fed production data, the specific energy consumption figures are calculated and displayed.
• The system can monitor up to 1024 (physical/electrical nodes based on LonWorks).
• The system has been demonstrated in various industrial sectors like Petrochemical, textile, paper & pulp, and engineering industries.

• The EMS can be used as a tool for energy accounting / analyzing in industries, sub-stations & commercial establishments
• The EMS system calculates the Specific energy consumption (SEC) Maximum demand and generates control signals for taking appropriate actions.
• Better utilization of energy in industry & Energy conservation
• Provide smooth operation
• Ensure safety for both operating personnel and the environment
