1 - The best and most economical way to control district heating network and boiler plants Finnish Russian Energy Days 2014 Esa Kaarlampi, Schneider Electric Finland Oy

2 Termis Operation Dynamic real-time overview of your network

3 Termis SCADA? District Energy Plant Distribution network 20 % 80 % Investment 3

4 An intuitive tool for operating and managing your DH Network Better overview and improved operation. By using live SCADA data the Termis model is transformed from a planning tool (called Offline) to a decision making tool, integrated in your day-to-day operations with instant and clearly identified benefits and economic advantages. Like GPS automobile navigation, Termis Real-time will advise you of problems in the network, no matter which turn you take. 4

5 How does it work? The operator does not require any in-depth knowledge of Termis. By scrolling back and forth on a simple button interface he can obtain the information he need such as pressure, flow and temperature for any given point in time - in the past or in the future. The Termis model is fed with live information from the SCADA systems. Different variables, such as supply temperature, return temperature, pressure and flow can be displayed. Effects of interventions, such as opening or closing of valves can be assessed by simulations, which reveal disturbances in consumer supply. 5

11 Termis advantages Termis is the most advanced, effect full and extensive simulation tool for improving system design and operation in district energy plants. Termis is the district energy plants tool for improving: Energy consumption and hydraulic performance While reducing: Energy cost Operation cost Customer complaints Capital investments 11

12 Production Scheduler The automatic Production Scheduler reduces your energy costs with approximately 2-5%, depending on the flexibility and the variation in fuels. Thus, improving not only your economy, but also reducing the CO2 emission. The use of the Production Scheduler will see fewer boiler start-ups. As a result of this the maintenance will be reduced leading to an extension of the life span of these units. 12

13 Accumulator Optimization Correct calculation of time delays in the network Correct calculation of heat accumulation, ensuring correct optimization, for example in the morning 13

14 Pumping Optimization This module is an extremely valuable Termis feature, which helps you determine, how the pumps within a district energy network should operate at any given time in order to minimize the total operating costs for the entire network. Termis then calculates the set values for the pumps, thus minimizing the total operating costs. The optimal solution adjusts according to the constraints, which has been defined for the set values of the control variables. 14

15 Temperature optimization Determines anchor points for the inlet temperature of the plants, so that the total heat loss in the network is minimized T 1 T min1, T min2 T 2 T 3 While at the same time ensuring comfort temperature at the consumers 15

18 Termis Optimization The underlying Termis model accurately calculates: Heat loss in the network Transportation time for heating from plant to consumer Storage capacity of the pipes and any heat storage tanks Smooth operation at minimum cost saves energy! 18
