Thesis on total factor productivity

The site was chosen because its strategic location, where the supplies of public and private services are adequate and labor supply and raw materials are readily available. Sources of Raw Materials The plant shall have its own sugarcane plantation near the mill and the plantation shall be adequate in land area that will produce the needed raw material for sugar. Availability of Transportation The plant site is strategically located in Sitio Maguindong, Luakan, Dinalupihan, Bataan where transportation is not a problem.

VFD eff, power factor and harmonics 3 itsmoked Electrical 15 Jun 08 It is whatever it is stated to be - in this case W verses the load. The losses are caused by the switching and a VFD does a ton of switching.

Thesis on total factor productivity

During this switching the actual devices get hot as they have voltage losses and current is passing thru them. Added to this loss is also the energy used to run the actual controls and the fan s. I would use The VFD losses are mostly the output transistor losses. The input rectifier is probably responsible for the second largest component of the losses.

The losses listed for the VFD would be for full load, full speed motor operation.

Some VFD losses, such as logic and fan losses, are constant regardless of motor load. Some losses are proportional to motor current and others are proportional to motor power. The VFD has a high displacement power factor.

Harmonic content is lower for VFDs connected to power systems that have higher source impedance lower short circuit current capacity. Harmonic content varies with motor load.

Input harmonic losses occur in the power distribution system and in the VFD input rectifier.

By John Mauldin

Adding an input harmonic filter reduces harmonic losses, but adds losses due to the extra components that carry the total VFD input current. The power factor at the output of the VFD is about the same as the motor power factor would be if it was connected directly to the power line.

That means that low motor power factor increases the DC bus cap losses and the transistor losses but not the input rectifier losses. No one much cares on the other side and it is also close to unity anyway.

VFD eff, power factor and harmonics

Power factor is how far apart the peak current waveform is away from the peak voltage waveform. NOT more energy just current. No one has to burn more coal or fuel to provide this added current but all the equipment between the power source and the load has to bigger to carry this extra current.

There are secondary issues like added voltage drop caused by these larger currents that DO actually consume more energy. The worst the PF farther from 1 the steeper the penalties.

Capital outlays that actually pay back. But wise thinking would still have you considering this. This actually forces the current and voltage waveforms into closer alignment.I LJUBLJANA UNIVERSITY FACULTY OF ECONOMICS MASTER’S DEGREE THESIS Management of the Supply Chain – Case of Danfoss District Heating Business Area.
