1.What is a frequency inverter?
A frequency inverter changes output voltage frequency and magnitude to vary the speed, power, and torque of a connected induction motor to meet load conditions. A typical frequency inverter consists of three primary sections.
2.Is it Frequency Inverter a critical part in your application?
For example if an intelligently and adequately designed mission critical multiple pump system with built in redundancy and backup is to be redesigned to utilize variable frequency system process control it follows that to continue to meet the mission critical aspects of the system design that the duty pump, the stand by pump and the backup maintenance pump (a common arrangement for public water supply utilities) should all have frequency inverters fitted. It will not deliver on mission criticality if only one frequency inverter is employed and switched between the three pumps. It would be foolish to think that only pumps fail, in this case if mission critical backup is required then that also applies to the frequency inverters, the associated switchgear and the control system.
3.How to select frequency inverter?
These guidelines dispel the confusion about matching Frequency inverters (Variable frequency drive) and motors to fans and pumps that are typically encountered in commercial building applications. While the motivation to increase energy efficiency could be financial (reduced energy costs) or ethical (reduce greenhouse gas emissions associated with power production), it is taken for granted that frequency inverters are an easy way to improve energy efficiency in a motor application. And with these noble intentions in mind, the engineer will specify a frequency inverter for his client. Oftentimes, that isn‘t the end of the story for the engineer.
4.How is frequency inverter saving energy?
1. How much process flow and pressure requirement through AC motors
2. Existing control methodology like control valve in pumps, Damper or guide vane for Fans & Blowers etc. and position of the valve or dampers
3. If you have process flow and pressure data and pump or fan design data, you can calculate energy saving using affinity law
4. Loading and Unloading cycle for compressor application. If the unloading time is higher for compressor application, you will get better energy saving
5. Using affinity law, you can calculate the energy saving with consideration of frequency inverter losses. With this you can calculate the Pay back of the inverters.
There are different ways you can use frequency inverter or soft starter to reduce your energy bill. Carefully analyses the possibilities of your plant.
5.How frequency inverter save money?
The frequency inverter main advantage is saving electricity, saving rate depends on the application and running time.
The other advantage is protecting the electric motor, you can see if a high power machine start, other machines will be effected like low voltage.
After you use frequency inverter to control the motor, the power grid line is more stable and no instantaneous current shock to the electric moto
