https://www.robiconperfectharmony.com/
Introduction
More than 20 power companies worldwide
U.S. power plants need to increase
Efficiency and throughput
Improve profitability. The utility is using
Low fuel, high emission machinery
Process control method for process control
Electric fan, pump flow
And compressor. Constant speed
Excessive influx of processing motors
Current during start-up, thereby limiting
The number of starts over a period of time, and
Make it difficult to precisely control
Processing speed.
challenge
According to the specific situation of each factory
Regulations, utilities want to reduce
Auxiliary power requirements
Achieve one of two results. result
One: Plants will burn like
Amount of fuel and create the same level
Emissions, but increased its net megawatt output
By reducing the auxiliary value.
Outcome 2: Less plants burn
Fuel and reduce emissions because
Requires less auxiliary power and produces
The same net MW output.
Life cycle cost is an important factor because
Utilities measured the return on investment of all new purchases
In 20 years. In addition, the utility
Want to reuse the original medium voltage
Constant speed motor, such as buying new
The motor will have a negative impact on the project's return on investment.
solution
Siemens local representative work
Close contact with utilities to collect the real world
Process operating parameters and execute
Calculate to compare power
Consume the existing constant speed
Medium voltage motor
Variable Speed Drive (MV VFD)
20 power plants. Siemens ROBICON
It turns out that Perfect Harmony VFD can provide
Save a lot of energy, and
Large ROI and low total cost
Ownership is due to its 20-year life expectancy.
Siemens Robicon was selected for this utility
For these reasons, the perfect harmony drive
And its built-in reliability.

Power companies improve fuel
VFD efficiency
Unique mechanical advanced battery bypass function can be realized
Possibility of the drive to keep running in rare cases
Power failure of the device. Other MV VFD technologies are closed
In this case, it may cause the entire
The power plant is closed. Due to opportunity cost
Other related to power plants that do not generate electricity
MV VFD technology has an extremely long return on investment,
The utility will not approve.
result
Siemens ROBICON Perfect Harmony improves fuel
The efficiency of all 20 factories. Net increase in some facilities
MW output power, other fuel consumption is less, thus increasing
Profitability. Since all 20 factories use the same drive,
Utilities benefit from spare parts supply and service
Align across positions.
benefit
