Abstract
Demand control is the concept of regulating the peak electrical
demand of a commercial, industrial or residential power system so
as to minimize the peak demand charges that must be paid by the
customer to the electric utility providing the power. This peak
demand is usually defined as the maximum average demand over a
15, 30 or 60 minute interval during the billing period.
The attention given to demand control has been rapidly
increasing due to increasing electricity rates and the
application of microprocessor technology to this concept. In
regulating his peak demand,- the customer desires to accomplish
the same amount of work as before. Some demand control has been
achieved through the optimum scheduling of electrical use while
additional savings can be achieved through conservation practices
(conservation practice also reduce the total energy consumed).
The practice of demand control by commercial and industrial
customers of electric utilities is experiencing increasing
popularity. This thesis explains the concepts of demand control
devices and implementation of device in paper converting plant
Kimberly-Clark Australia - Warwick Farm Mill. The device has
achieved the anticipated savings and payback. An installation of
device at electricity consumers on KVA demand charges should be
consider in conjunction with power factor correction equipment.
