— Power Controller
Benefits Thanks to the Tmax XT with the embedded Power Controller, the following benefits are guaranteed: • Reduction of energy costs with minimum impact The loads are disconnected from the power sup- ply for short periods, in the minimum number necessary and in a fixed order of priority, en- abling power consumption peaks to be limited. This allows the contract drawn up with the energy provider to be renegotiated, reducing the power allocated, with a consequent reduction in total energy costs. • Power limited only when necessary The Power Controller function manages up to four different time bands. It is therefore possible to re- spect a particular power limit according to whether it is during the day (peak) or night (off peak). In this way, consumption during the day when rates are at their highest can be limited. • Easy of use The Power Controller function allows the installa- tion to be managed efficiently with a simple ar- chitecture. Thanks to a patented design, it is suf- ficient to measure the total power of the installation without having to measure the power consumed by each load. Installation costs and times are thereby reduced to a minimum. The Power Controller function does not require the writing, implementation or testing of compli- cated programmes for PLC or computer because the logic has already been implemented in the protection unit and is ready to use. It is sufficient to set the installation parameters from a smart- phone or directly from the switching device dis- play.
Thanks to the integrated communication mod- ules, the Power Controller can receive the maxi- mum absorbable power directly from the medium voltage control system, determining consump- tion for the next 15 minutes. According to the in- formation received, the Ekip Power Controller manages the switching off of non- priority loads or the switching on of reserve gen- erators. The software gives maximum priority to non-programmable preferred energy sources, such as wind and solar, and they are therefore considered uninterruptable. In the event that the production of internal power to the controlled network is reduced, due, for example, to de- creased production of solar power, the Power Controller will disconnect the necessary loads to respect the set consumption limit. This benefit is used, for example, in installations with a system of cogeneration. Indeed, the Power Controller controls the total consumption drawn from the electrical network, disconnecting non-priority loads when generation is reduced and reconnecting them when generator power is sufficient not to exceed limits. There are multiple advantages of the system including: reduction in energy costs, maximum use of local generation and greater overall energy efficiency.
