Power Plant Loads and Diagrams This technical article will shed some light on the basic diagrams and arrangements for the supply connections to the generator voltage, above the generated voltage, and some basic transmission diagrams. It is important to note that the choice of electrical layout for the proposed power plant depends on the prevailing conditions locally. The engineers involved in designing the power plant must take into consideration the nature of the load. And the need to maintain the continuity of service. It should be as simple as possible to arrange in order to ensure the required flexibility in operation and to provide the appropriate facilities for inspecting the equipment. A review of the existing supply installations shows that the combinations shown are myriad, but the analysis indicates that in general, they are combinations of a limited number of basic schemes. Arrangements vary from the simplest single circuit scheme to the duplicate embedded systems installed in large cities where the importance of maintaining continuity of service justifies the high capital expenditures. It is important to note that the scheme chosen for power plants distributing power at bus voltage differs radically from the design that would be desirable for a station designed for mass transit. In some installations supplying urban underground cable systems, discrete phase diagrams have been used and are still used to ensure maximum reliability in operation. However, their use appears to be declining, as the improvement in performance compared to conventional adjacent phase assembly is not better enough to justify the additional cost. However, this statement is adopted from country to country, and this is especially important in light of the continuous improvement of protection equipment and the most reliable relay schemes available today to remove defective equipment, buses, or circuits.
