- apply the P Petrick’s method to find the minimum SOP solutions for below question. f(a,b,c,d) = ...arrow_forwardA polyphase system is generated by______? a.Both a and c b.Having two or more generator windings separated by equal electrical angle c.Having generator windings at equal distances d.None of thesearrow_forwardWhich one of the following d-c machine losses is determined by applying a standard value rather thanby measurement?A. Friction and windage lossB. Core lossC. Copper lossD. Stray-load loss Note: I have doubts if it is the letter B or the letter D, can you help me in this question, thanks.arrow_forward
- Solve for the nodal voltages and the power consumed by the passive elements.arrow_forwardDefine derating, why must a 60Hz generator be derated if it is to be operated at 50Hz? Find percentage of derating done. (4) A generator connected with an infinite bus bar, the frequency indicator shows that frequency is decreasing from 50Hz. What action you will take for restoration of frequency. (2) A generator is loaded with certain load, and its voltage regulation is very poor. What are various ways by which you can improve its regulation? (2)arrow_forwardplease detailed equation soultion , and why V*R instead V/R in nodal equation?arrow_forward
- Since R1=18.10Kohm, R2=67.58Kohm, RC= 1.08Kohm, RE= 3.23Kohm, VCC=14.00V, Beta=241.00 in the circuit given in the figure, calculate the IC current by doing a complete analysis. When performing your operations, 2 steps will be taken after the point. choose the closest one from the stylish ones according to the +/-10% margin of error. There is only 1 correct answer to the question.arrow_forwardı know answer but how? z=2, p=1,n=1 and system is unstablearrow_forwardSuppose a power system consists of two isolated regions: a western region and an eastern region. Five units have been committed to supply 3090 MW as shown below. The two systems are separated by a transmission line that can handle a maximum transfer of 550 MW in either direction. If losses are ignored, calculate the spinning reserve for the overall system and for each region. Comment on the adequacy of the spinning reserve of the overall system, and for each region. (consider the effect on the power supply in each of the regions if the various generators fail). Repeat the above calculations and analysis if an average of 8% of the output of the generators is lost in the transmission and distribution system before reaching the load.arrow_forward
