摘要

The application of Symphony spreadsheet programs to electrical machine analysis is described. Seven typical examples are presented, namely steady-state performance of a DC shunt generator, speed control of a DC shunt motor, magnetizing current waveform of a transformer, steady-state performance of a three-phase induction machine, frequency control of a three-phase induction motor, induction motor run-up, and swing curves of a synchronous generator. Advantage is taken of the spreadsheet environment for such operations as tabular calculation, table lookup, numerical integration, and what-if analysis. Extensive use is made of the integrated graphics facilities of Symphony for producing good quality screen displays on a personal computer, which proves very convenient and useful for computer-aided instruction. Certain features of Symphony are described in the context of the applications described.
