## 抄録

The Dalton-Cameron method is well-known as a method for determining direct and quadrature axis subtransient reactance (<i>x<sub>d</sub></i>" and <i>x<sub>q</sub></i>") by standstill response testing. This method entails calculating <i>x<sub>d</sub></i>" and <i>x<sub>q</sub></i>" from the voltage and current measured when a rated-frequency single-phase voltage is applied to each armature winding (U-V, V-W and W-U) in turn. The authors have developed a new method to calculate <i>x<sub>d</sub></i>", <i>x<sub>q</sub></i>" and the impedance loci by means of applying a D. C. voltage instead of a single-phase voltage, and named it the expanded Dalton-Cameron method. This method is a small-capacity standstill test, and is carried out by the following three steps. The first is to short-circuit the U and V terminals while a D. C. current flows between these terminals, to measure the voltage and current (<i>V<sub>DC</sub></i> and <i>I<sub>DC</sub></i>) when the D. C. current flows between these terminals, and to record the D. C. decay current (<i>i</i>(<i>t</i>)) after these terminals are short-circuited. This same procedure is also performed for the V-W and W-U terminals in turn. The second is to draw the impedance loci from the measured <i>V<sub>DC</sub></i>, <i>I<sub>DC</sub></i> and <i>i</i>(<i>t</i>) by means of Fourier transformation, and to divide it into the directand quadrature-axis impedance loci (<i>Z<sub>d</sub></i>(<i>js</i>), <i>Z<sub>q</sub></i>(<i>js</i>)). The third is to calculate from <i>Z<sub>d</sub></i>(<i>js</i>) and <i>Z<sub>q</sub></i>(<i>js</i>) values of <i>x<sub>d</sub></i>" and <i>x<sub>q</sub></i>" and the starting performance on the basis of two-reaction theory. Experimental and calculation results on starting performance as well as a comparison with calculation results of <i>x<sub>d</sub></i>" and <i>x<sub>q</sub></i>" by Dalton-Cameron method clearly show that this method is very useful.
