All Rights Reserved, Sign up for promotions and equipment sales. A guide to DP electrical power and control systems September 2016 Rev. The thyristor devices most commonly used to control the power in a load are: Thyristors are switching devices. Once turned on, these devices offer very little resistance and hence dissipate very little power, resulting in high efficiencies. 1) Power system metering 2) Power system protection 3) Power quality 4) Power system dynamic performance (system stability analysis and controls) 5) Power System Operations, Planning & Economics Phase-control circuits produce radio frequency interference (RFI) and most controllers produce non-sinusoidal waveforms that tend to generate harmonics in the supply. They are triggered (switched) on by a current pulse through a gate terminal. This is termed ‘poor load regulation’ and may be overcome by using automatic voltage regulators, but this becomes very expensive when the load power is high and still does not overcome the poor efficiency of the method. We can test and repair your existing equipment, provide you with spare equipment to keep production running, and even offer rental service for short-term projects. electrical power synonyms, electrical power pronunciation, electrical power translation, English dictionary definition of electrical power. It is unsuited to inductive loads. An example of a Power System is the Electrical Grid that provides power to homes and industry within an extended area.

The disadvantages are that it is very inefficient, bulky, very expensive (when the running costs are taken into consideration), and has poor load regulation. Harmonics induced by these nonlinear loads are a potential risk if they are not predicted and controlled. Rheostat control uses a series-connected rheostat (variable resistance), as depicted in Figure 2, to control load power. To minimize RFI, the thyristor is switched as the supply voltage crosses zero or is at zero volts. The ABS Guidance Notes for Control of Harmonics in Electrical Power Systems has been developed It has a limited number of adjustments and effectively adds impedance in series with the load. This method of AC power control has the advantage that it is very simple. Electrical engineer working at control room of a modern thermal power plant. Apart from poor efficiency, an undesirable aspect of this method is the manner in which the load voltage varies if the load current varies. This method is suited only to resistive loads such as heating elements. However, for a wide range of control the rheostat may be physically very large; it may in fact be larger than the load. The electric power is produced by the generator and can also be supplied by the electrical batteries.
