This is unhealthy for installations of power system. The proposed embedded system drive is used to reduce the cost of the equipment and increase the efficiency of the system. Experimental results of the proposed systems are included. It is better choice for effective cost process and energy savings.
Introduction This paper proposes the following solutions to correct the power factor. The inductive load is act as a from capacitors. The reactive electrical energy conservation. This improvement of power factor is helps to the efficiency of the power system.
The existing work on power factor correction is solid devices. In this proposed system is used to rectify the above problem. Power factor is the cosine 2.
Theory angle between the voltage and current. This current and voltages are sensed by using instrument transformers like a. Power factor current transformer and voltage transformer. In this proposed Power factor indicates actual amount of power is delivered method zero crossing detectors is used to converting the to the load. The phase angle between the Apparantpower voltage and current is calculated by inbuilt computers in the microcontroller.
The calculated values are comparing with actual load present in the system. The load on the system is maximum The direction of the current and voltage vectors are not when the capacitor bank is added in the system by using same at all loads like inductive, resistive, and capacitive micro controller.
These processes are continuously carried loads. Resistive load kirbakaran yahoo.
All Rights Reserved between voltage and current. So the power factor is unity M. Ravindran et al. Performance of the Proposed System c. Inductive load The following functions are to be considering for the Current vector in the pure inductive load is lagging behind proposed system. Practically pure transformer like potential and current transformers.
Capacitive load 4. Experimental Setup Magnitude of the voltage and current are fed into themicrocontroller89C It is used to measure the phase shift between the voltage and current. According to the power factor number of relays is energized or deenergised. The signal from microcontroller either 0 or 1 is used to operate the relay.
The relay contacts are closed when the capacitor is Current vector in the pure capacitive load is leading in front connected to the circuit through relay.
Hence the power of the voltage vector with angle 90o. It is also having low. Hence angle of leading is not exactly 90o Figure 1.
