Automation had always been associated with the improvement of production processes, achieving higher quality in production and reducing costs were until now the main objective. There is increasing awareness about energy issues and new alternatives are being sought to produce energy without having an environmental impact. On the other hand, and as important as the previous one, it is to use the available energy resources in an “optimal” way, and this should be one of the objectives of the automation engineer. There are a series of simple techniques for implementing processes, and with extensive documented experience, which are listed below: Savings in electrical energy in industry Power Factor Control (cos φ) It is one of the best-known techniques due to the strong penalties that electricity companies apply to their customers for having a low cos φ. The main problem is in the apparent consumption of our installation, since there is energy consumption that is later returned to the network.
Although we cannot really talk about extra energy consumption, losses do occur due to the Joule effect in electrical cables and the oversizing it entails in electrical substations. The Saint Helena Email List solution is relatively simple, just place a “capacitor bank” to correct this effect. Due to the extra costs that the electricity companies impose, it is a quick payback installation, sometimes less than a year. High energy efficiency motors and frequency converters “The drives consume almost 70% of the electrical energy supplied to an industrial plant. In the European Union alone, the application of frequency converters and high-efficiency motors would save 43 TWh of energy, equivalent to 3 billion euros or the energy that would have been provided by 19 power plants burning fossil fuels.
The expense incurred for an electric motor, in an estimated life of 12 years, taking into account the costs of acquisition, installation, maintenance and energy, can mean that up to 96.8% of these costs are related to energy consumption, an amount that can reach up to 99% if its life reaches 20 years. The techniques used to improve the efficiency of the motors involve reducing the resistivity of the electrical wiring of the rotor and stator.To do this, and to continue maintaining the physical size of the motors, we have to go from aluminum to copper. On the other hand, improving aerodynamics and friction, and ferromagnetic losses in the iron of the core are other techniques to improve performance. As an example, in the water pumping plants in Madrid, Picadas I and II, and Plaza Castilla, their new installations amortized in less than 2 years by increasing the performance of the motors from 92% to 97%. In the same way, although more difficult to compare, is the use of frequency converters to manage motor starts and stops. The savings may, in some cases, be such that their amortization is in a few months.
