EM-SCADA Control and Data Acquisition System Software for Electrical Machines
The Control and Data Acquisition System of Electrical Machines, EM-SCADA has been developed to study, analyze and investigate the performance of rotating and static electrical machines such as three-phase induction motors of squirrel cage, Dahlander motors, induction motors with starting capacitor, induction motors with wound rotor, reluctance motors, synchronous generators, DC motor-generators, three-phase and single phase transformers, etc.
The Software Control and Data Acquisition System for Electrical Machines, EM-SCADA has been developed by Edibon to study and analyze the performance of rotating and static electrical machines such as three-phase and single-phase AC motors, synchronous generators, DC motor-generators or three-phase and single phase transformers.
The EM-SCADA is designed to work with both rotating electrical machines and transformers. For this purpose, this system has an interface for the acquisition of data of all control and power signals, which are acquired and analyzed with the SCADA System afterwards
In the case of rotating machines, the interface has the corresponding connections to control a servomotor that is coupled to the motor´s shaft to be tested. The included SCADA Software has several algorithms, which allow the user to transfer different load profiles to test electric motors under different load conditions. In this way, it can be simulated different load profiles with lineal, constant or exponential slope. During the motor testing procedure with the servomotor working as load, electrical and mechanical parameters are monitored in real time (currents, voltages, power, torque, speed, etc.) to obtain the corresponding results ( torque vs speed curve, performance etc.).
In order to carry out transformers testing, the interface has the properly connections to fulfill the electrical parameters measurement when undergoing unloaded and short-circuit test. The results are stored for further analysis with the SCADA System.
