— The exclusive Power Controller function available on the new Emax 2 units monitors the power, keeping it below the limit set by the user. As a result of this more effective use, the peak of power consumed can be limited allowing savings on power bills. The Power Controller, patented by ABB, discon- nects non-priority utilities, such as electric car charging stations, lighting or refrigeration units, during the times when consumption limits need to be controlled, and reconnects them once limits are in check. When required, it automatically activates auxiliary power supplies such as generator sets. No other supervision and control system is required: the required load limit can be set on Emax 2, which can control any switching device located down- stream, even if it is not equipped with a measure- ment function. Application examples Power bill savings, demand response, power over- load avoidance are the typical reasons for adopting Ekip Power Controller. The Ekip Power Controller is a common solution for office buildings, shopping malls, hotels, college campuses, waste and water industries and any plant that works like a low voltage microgrid.
Ekip Power Controller, which can be used with all Ekip Touch trip units in the Emax 2 series, effec- tively helps to improve energy efficiency by manag- ing the entire low-voltage electrical system. In fact, it is able to adapt the demand for power according to the availability of the energy source, the time of day and the costs indicated in the current pricing plan. Therefore, the Ekip Power Controller is able to maintain power consumption within the limits de- fined, thereby optimizing the costs of managing the installation and reducing emissions. The command sent to the downstream devices can be performed in two different ways: • through the wired solution, by commanding the shunt opening/closing releases or acting on the motor operators of the loads to be managed; • through a dedicated communication system. The ability to control the loads according to a list of predefined priorities provides significant advan- tages, both economic as well as technical: • economic: energy consumption optimization is focused on the control of the costs linked in par- ticular to the penalties that are levied when the contractual power is exceeded or when the con- tractual power is increased by the Distribution System Operator (DSO) as a consequence of ex- ceeding the limit repeatedly. • technical: the possibility of power absorption over the contractual limits for shorter periods and, as well as, the management and the control of the power consumption over long periods of time. Thus it is possible to reduce the likelihood of malfunctioning due to overloads, or worse, complete inefficiency of the entire plant due to tripping ofthe LV main switching device.
