Three generating units within a power plant are synchronized and supplying power to the main grid. The table below shows the respective capacities, initial loading and %droop of each generator for a grid frequency of 60 Hz. Generator # G1 G2 G3 Speed Droop 3% 4% 5% Capacity (MW) 50 100 150 Total 300 MW Initial Loading (MW) 20 60 120 200 MW 6 1. What will be the output of G2 if the grid frequency drops by 0.3 Hz? 2. What will be the total output of the power plant if the grid frequency dropped from 60 Hz to 59.8 Hz? 3. What value of grid frequency will cause G1 output to increase from 20 MW at 60 Hz to 25 MW?

Three-Phase Transformers

Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.

Transformer

Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
