ENERGY OPTIMISIATION BY MEANS OF LOAD MANAGEMENT
Let us examine the power supply tariff (Pmax).What do we understand by this value, and
how is it determined?A high peak-load occurs when several energy-intensive users are consuming power at the same time.
The load-peak Pmax is the average of a series of readings taken over a period of 15 minutes.The highest of these fifteen-minute-average readings is used to determine the power consumed for monthly invoicing purposes, and is reflected in the tariff for the month concerned.
Most contracts entered into since 2006 are based on an annual price of power consumed.This means that the fifteen-minute-average value, if it is obtained only once a year, has an unfavourable influence on the total annual energy bill.
These peak loads can be avoided,by properly-coordinated shutdown or regulation of specific consuming items, in relation to the energy being supplied to them.Load-profile measurement is used to identify which of these consuming items can be shut down.Smooth production can be maintained if shutdown is carried out on a relay basis.
You can carry out a simple calculation to determine whether your operation is affected by excessive peak loads, by filling in the following fields.The average value is then compared to the peak load.If there is a wide difference between these values, it may be worth your while to implement a load-management system.
