Savings with Frequency Converters
Connecting frequency to the motor already provides a significant gain in financial costs. This happens due to:
- energy savings;
- reduced likelihood of equipment failures;
- optimization of the operation modes of technological installations;
- lower labor costs for operation and maintenance.
The frequency converter realizes all its capabilities by operating at maximum efficiency.
Example of Using Frequency Converters
One of the most common cases for using frequency converters is in pumping systems and stations. Part of such systems includes several pumps that are activated depending on the load in the pipeline. The pumps can operate:
- alternately for optimal use of their resources;
- together, connected in a cascade to regulate power.
Typically, such systems include one or more backup pumps for emergency situations.
Automatic Control Systems
In such cases, a single converter is often insufficient. Although several hardware-software solutions have been developed that can function with just one device in some cases, a control system (ACS) is usually required that can effectively manage a group of pumps. Both the manufacturers of converters themselves and engineering research centers have developed ready-made solutions for software and hardware that ensure the effective operation of several identical or different frequency converters.
Advantages of Automatic Control Systems
Automatic control solutions have a wide range of advantages compared to systems without ACS, including:
- increased system reliability;
- reduced energy costs;
- improved condition of equipment;
- ease of operation.
