D.C. and A.C Drives with SCADA system.
As the A.C. and D.C. motors are more and more used for variable speed applications to precisely control the speed of motor, A.C and D.C. drives are progressively used for these applications. SCADA (Supervisory Control and Data Acquisition) application is used to provide human machine interface (HMI) to operator to observe various system parameters and also feed various control parameters to control the drive. SCADA system also consists of PLC (Programmable Logic Controller) which calculates the actual control parameters from data fed by operator through HMI.
