Throughout most industrial operations, electric motors play a critical role in driving conveyor belts, pumps, compressors, agitators, fans, and other critical infrastructure assets. As the number of motors in process plants increases, management and monitoring of such assets is critical in preventing core process errors such as the proper mixing of ingredients. Motors also account for about 70 percent of the total energy consumed in a process plant. A strategy that links motor control, automation, and energy management, therefore, can help plants to simultaneously reduce costs while increasing production.
Motor failure can be expensive as it can cause plant stoppages, damage to equipment, and risk to people or the environment. Robust connection and communication between the motor and the automation system plays an important role in minimizing instances of motor failure. In addition, overall energy costs are reduced when energy data from motors is monitored so that function can be better aligned to workload.
Most companies fail to pursue the strategy of Integrating motor control, automation, and energy systems because of the perceived technical complexities. However, seasoned systems integrators with knowledge in all three of these domains can help plant operators to combine and optimize these systems, thereby helping to drive profitable production.
Improved motor operation and uptime can be achieved through several approaches that can be used in tandem with the automation system for performance optimization. Here are some components that can play a role in improving motor reliability, efficiency, and uptime:
When we at Supertech, an automation systems integrator and certified Schneider Electric Alliance Partner for Control System, Hybrid DCS, Intelligent MCC, and EcoXpert, engage in industrial automation systems and energy solution integration projects, we are often asked to advise the best approach for designing and implementing motor control solutions. Listed below are some important hints and tips for deriving the full benefit from MCC-related investments:
An intelligent MCC is much more than just a metal box with electronics inside. In the digital solution era, where data plays a critical role in optimizing operations, the value of the intelligent devices inside the panel is what really counts. The components are intelligent and hence require configuration. Many panel builders do not possess these skills and they often produce panels that can run the motors in local mode but cannot communicate with automation systems. Such a situation (inadequate communications configuration) can cause costly delays during plant commissioning. Users should ensure that the systems integrator who designs and configures the MCC has the expertise, track record, and certification from the manufacturer to perform the necessary work.
Three levels of buses are available for communication back to the automation system–Modbus (RS-485), Profibus or Canopen, and Ethernet.
Intelligent motor control provides energy consumption data for each motor. Multifunction meters and intelligent breakers are used for monitoring the quality and quantity of electrical energy. Data from all these devices can be captured by energy monitoring systems such as Schneider Electric’s Power Monitoring Expert (PME) and Power SCADA Operations (PSO). These systems output management information reports and dash boards, which help to significantly reduce energy costs.
