In order to implement the optimal dispatch of elevator group and reduce elevator energy consumption,a new prediction method is presented based on the ARMA model prediction and the RBF neural network model prediction.

The influence of the pulse power and the direct-current power on the power consumption and the COD removal in wastewater electrolysis process was studied,and the causes of energy conservation and high efficiency of pulse-electrolysis in wastewater treatment were analyzed.

constant direct current) on power consumption and effectiveness of electro coagulation treatment of a kitchen wastewater (COD=400-700 mg/L).

It can supervise the power consumption,which offers the technological supports for the production,management,and decision-making.

According to these factors, the amounts of electric energy consumption are cut through technology and equipment management.

To research the factors influencing the power loss of the ozone generator,this paper analyzes the main power loss in the generator.

With the increasing of voltage grade of power system,the power loss at ground wire becomes more and more remarkable.

In order to reduce the inductive current and the power loss caused by the current when the power system runs naturally, this article brings forward a way to reduce the power loss through a multiple impedance to insulate the lightning shield line and ground, so that the system can run economically.

Regulating disequilibrium load and decreasing electric energy loss;

This method has reduces the electric energy loss and voltage drop.

For excessive electric energy loss in distribution network in our country,optimal control of reactive power is put forward in distribution network to decrease the line loss and increase the energy utilization rate.
