2(a) (i) Consider two generating units, rted at 300 MW and 500 MW, with 6% and 4% speed droop. respectively, operating at 60 Hz and supplying a total load of 700 MW. If the load were to decrease by 100 (8 points) (Bonus question:) Briefly describe the role of the rotating spring and fly-weight assembly in the servo- (4 points) MW, what would the new frequency be before any supplementary control action occured? (ii) assisted speed governor.

A system consists of two plants connected by a transmission line
and a load that is located at plant 2. Data for the loss equation
consists of the information that 100 MW transmitted from plant 1 to
the load results in a loss of 10 MW and
where B11 is the only non-zero loss coefficient. Assume that the
incremental fuelcosts can be approximated by the following
equations:
Find the required generation for each plant and the power
received by the...

6. Short Questions (10 x 5 = 50) a. Why 39 AC system is used in power transmission, why not 10, 20, 49, 50, 60 or any other combination of AC systems? b. Mention four factors to control power flow to the load bus. Why two of these are controllable and the other two are not? c. Suppose you need to transmit 300 MW of power between locations A and B, which are 150 km apart. What level of transmission...

Generation Question 1 to 5 relate to the following grid connected generator. A governor-controlled, steam-driven 450 MW synchronous generator with 5% droop is synchronized to the 60 Hz grid and its load set-point adjusted to deliver 300 MW to the grid. Q1. (a) 000 What is the actual droop of the generating unit? 0.0225 Hz/MW (b)...

Power economic schedule, economic dispatch question
Problem 02) The system to be studied consists of two units as described as follows. Assume that the fuel inputs in MBtu per hour for units 1 and 2, which are both on-line, are given by H = 8P+0.024P2 + 80 H, = 6P, +0.04P + 120 Where, H = fuel input to unitn in MBtu per hour (millions of Btu per hour) (n = 1,2) Pr = unit output in megawatts (n =...

Consider two generating units with input-output curves Unit 1: coal-red steam unit: H1 (P1) = 500 + 8P1 Unit 2: gas turbine: H2 (P2) = 210 + 7P2 and operating limits Unit 1: 150< P1 < 500 MW Unit 2: 100 < P2 < 250 MW Suppose the fuel costs are Coal: $3.50/MBtu Gas: $2.50/MBtu and the load is L = P1 + P2 = 600 MW. Both units are on so that unit 1 must supply at least 150...
a) The fuel costs of two operating units are as follows: c1=0.05P12 + 25p1+400 US$/hr c2=0.1P22 + 25p2+350 US$/hr If given that the minimum and maximum powers are 10MW and 1000MW for each unit, compar...
a) The fuel costs of two operating units are as follows: c1=0.05P12 + 25p1+400 US$/hr c2=0.1P22 + 25p2+350 US$/hr If given that the minimum and maximum powers are 10MW and 1000MW for each unit, compare the cost of the allocation of generation(dispatch) through an optimal strategy against an equal-share of generation strategy for a load of 100MW. Hence calculate the net loss/gain of the optimal strategy against the equal-share strategy b) The load for the power system consisting of two...
