Program logic demand control system

The present invention is an external connection to, in particular digital integrating and receiving a signal from a watt-hour meter compare the total demand for power and a predetermined target amount of power when the contact control of each load, each load related to a programmable logic-based smart maximum power management system maximum power management unit for controlling and monitoring the amount of power consumed by at suyongga to identify a control state of the load control the maximum demand of mainly controllable load suyongga below the amount of the target program by the strategy; And applied to the maximum power management device and by connecting the screen to the power usage based on the electric power information to be transmitted and received database over the network, predicting the amount of the future, and setting the controllable target amount of power based on the amount of the future to the maximum power management device that consisting of the communication server sending to be characterized. Accordingly, the invention is in the external user or administrator simple programming via a built-in programmable logic control processor that can be configured to control the sequence and delay match the high rate characteristics, and more precisely by controlling the load in a more efficient steady load operation as well as possible, it is not necessary to use the load control circuit that was used in the existing configuration can be simpler and reduce the cost and time required for manufacturing the load control circuit.
