Q. Two three-phase generators are supplying to a common balanced three-phase load of 30 kW at 0.8 power factor lagging. The per-phase impedance of the lines connecting the generator G1 to the load is 1.4 + j1.6 , whereas that of the lines connecting the generator G2 to the load is 0.8 + j1 . If the generator G1, operating at a terminal voltage of 800 V (line to line), supplies 15 kWat 0.8 power factor lagging, find the voltage at the load terminals, the terminal voltage of the generator G2, and the real power, as well as the reactive power output of the generator G2.
Q. The external - characteristics data of two shunt generators in parallel are given as follows: Load Current, A: 0 5 10 15 20 25 30 Terminal voltage I, V: 270 263 254 240 22
Disadvantages of SDR 1. Power consumption is more due to rapid switching of modes 2. Hardware design is not easy 3. Software bugs exist in the system
Hardware Requirement- Server of adequate sizing for enterprise-wide deployment for storing maps and geospatial data. Application server and web server. Desktops
