Abstract: The power IRP/DSM integrates power -saving planning with exploitation of power resources, and lowers construction investment of power systems and charges for electricity through reasonablely using power resources and reducing power consumption. Oil refining and chemical engineering enterprises could use the follows for reference: deploying energy-saving lamps and frequency converters, applying new energy - saving highly-efficient pumps and air compressors, generating power with residual heat, raising the power factors of electric networks.
