In response to the recent rapid increase in power demand, Chubu Electric Power is now constructing two 1,650-megawatt power plants, each consisting of seven single-shaft combined-cycle units. These will be plant Nos. 3 and 4 of the Kawagoe Power Station.

As one unit of plants, these power plants not only will be among the most powerful (in output) in the world, but will also offer the following features:

1) The main equipment of these plants, a gas turbine, will be a GE-Hitachi Model F7FA, the state-of-the-art 60 Hz model, for large equipment capacity and high efficiency. The heat recovery steam generator of each plant will use serrated fin tubes for high efficiency and compactness.

2) Plant efficiency will be at least 48.5% by means of optimizing the combined-cycle system and using the single-shaft triple-pressure reheat cycle.

3) As middle-load thermal plants, these plants are designed to use the advantages of a single-shaft combined cycle, thus offering operational convenience.

4) For global environmental preservation, which is nowadays an important concern of the local community, these plants are designed to reduce NOx emissions, warm discharge water, and noise.

5) To save labor for operation, and to improve its man-machine interface, these plant will utilize a large screen and CRT operation.

Selection of these units and systems has entailed various feasibility studies and simulations for optimization, as well as new developments and reliability verifications.

This paper takes the example of plant No. 3 to describe how the method of system selection and to present the design outline.
