Electrical Distribution Feeder Analysis

\emph{Testing Strategy:} The graph between applied load in the range 0.5 grams to 575.5 grams and change in voltage is plotted. The graph obtained (see Figure~\ref{f:olggraph}) shows the inconsistent readings at many points for different combination of force applied. Also, the best curve equation is close to cubic, which is indication of bad design.\\*

The variables been shown in the simulater are the voltage, current, and ressistance. V(volts) = I(Ampers)* R(Ohms).

15. Load transient response is simulated under load variations from 0mA to 50mA that step load current has 100ns rise/fall times. The maximum overshoot and undershoot is 45.2mV and 30mV, respectively. It is evident from Fig. 15 which settling time is less than 5.65µs which provides fast settling time in compare with previous works. Line transient response is demonstrated in Fig. 16. As it is evident that the maximum variations at the LDO output are less than 7.4mV under loading condition of 50mA with the step voltage source from 1.8V to 2.2V with 500ns rise/fall

was derived and a relationship between Vinv and Vc was obtained (see Fig. 2). Applying voltage balance

The objective in Lab 3 is to experiment with different voltage and current values for series and parallel circuits under given circumstances.

It is observed that the power factor is maintained closer to unity when the input voltage is reduced from 230V to 110Vrms. Figure 11 (a) and (b) shows the power factor correction of controller for various load condition such as 20% (60W) and 75% (230W). The power factor for the system is found to be 0.84 for light load condition and 0.99 for full load condition. The THD of input current at full load with predominant third and fifth harmonic components are shown in Figure 12(a) and (b).Third harmonics is found to be 4.8% and fifth harmonic component is 4.9% which are well within IEC 61000-3-2 standard during wide range of load variations. The variation in power factor with load is shown graphically in Figure 13(a). It can be inferred from the graph that improved resettable control operates at high power factor for all load condition whereas the conventional PI control has poor power factor under light load conditions. Figure 13(b) shows the comparison between the efficiency of the converter for varying load conditions with the conventional control method and the resettable integrator control. The converter’s efficiency is maintained at 92% for light load conditions and 96% for fully loaded condition with integrator control technique. Thus the improved resettable integrator controller provides a very simple and reliable solution for power factor correction and

The mean voltage of the battery terminals while connected to the identification resistors is presented in Figure ‎4 12. These samples have been pulled out from the voltage sensor of the PEB panel. The voltage decreased as expected from 12.53 to 12.5 during first 20 seconds of connection to the

This chapter discusses the procedure followed and the assumptions made while setting up the design point and part load simulation. The NPSS solver uses a set of independent and dependent variables that is declared by the elements and the user. The independents are varied with each solver iteration until the dependent variables satisfy their specified condition [22].

Algorithm divergence theorem with the control node centered method has been noted by Kanal (2014) to be most trustworthy way of analyzing the electric field in engineering process. This kind of analysis gives the accuracy and stability of the simulation which obtains the tetrahedron solution that involves the system linear

Figure 4.2, located below, shows a comparison of the experimental data with the ANSYS data for the members in tension: the members in tension are members 14, 16, and 19 in Figure 4.1. Data points represented with a dot are data points taken when the load was

DC circuit analysis and design, play a massive role in electrical engineering and without the correct application of theory and practise in unison, nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability to analysis a circuit gives a potential electrical engineer the ability to learn how to problem solve in a theoretical and practical sense which in turn develops industry skills in which will follow them for life, and allow a solid knowledge base

The 220/66/11 kV SRS Chitradurga substation located near Chitradurga, old Bangalore road, Karnataka, India has been chosen for adequacy analysis. This SRS substation as a capacity of 220kV and it is step down to 66 and 11 kV using step down transformers.
