‏ You assume that a power system consists of four generators and seven loads . The number of buses is thirteen . Each bus is connected to two buses in the system . Calculate the number of nonzeros in the Jacobian matrix and the number of nonzeros in the bus admittance matrix for this system . Why is a slack bus needed in the power flow analysis ?

A system consists of 4 identical 250MVA generators feeding a load of 510MW. The inertia constant H of each unit is 2.5 on the machine base. The total load varies at 1.4% for a 1% change in frequency. If there is a drop in load of 10MW, determine the system block diagram expressing H and D on a base of 1000MVA. Give expression for the speed deviation, assuming there is no speed governor.

Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 37% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below. a. Find the probability that both generators fail during a power outage. ????(Round to four decimal places as needed.)

A hospital has three emergency generators for use in case of a power failure. Each generator functions independently, and the manufacturer claims that the probability that each generator will function properly during a power failure is 0.95. 1. List all of the possible outcomes in the sample space, S, and find the probability associated with each outcome. 2. Define the random variable X = the number of generators that fail. Calculate the value of X for each outcome in the...
