Experimental determination of synchronous machines reactances from DC decay at standstill

Measurement of Certain Synchronous Generator Parameters by Field Discharge Method Using Regular Excitation Systems Elements

“…Для их экспериментального определения в соответствии с ГОСТ 10169-77 применяют методы, основанные на опытах гашения поля [5,6], известные в мировой практике как DC decay Test [7][8][9][10][11][12][13][14][15][16][17]. Методы позволяют проводить измерения большинства параметров схемы замещения, в первую очередь реактивных сопротивлений и постоянных времени.…”

Synchronous machine parameter identification by various excitation signals

“…In this section, the practical aspects of measurements are described and machine conditions for standstill tests are also given [15][16][17]. The tests are described in IEC34-4A and ANSI-IEEE Std.115A publications [4,5].…”

Synchronous machine parameter identification in frequency and time domain

“…Using the Park's d and q -axis reference frame, the synchronous machine is supposed to be modeled with one damper winding for the d -axis and two windings for the q -axis ( 2 2 × model) as shown in Fig. 1 [6][7][8][9][10].…”

“…The more common representation is the one deduced from the second order characteristic equation which describes the 2x2 model [8][9][10] Damper circuits, especially those in the quadrature axis provide much of the damper torque. This particularity is important in studies of small signal stability, where conditions are examined about some operating point [10].…”

“…In this section, the practical aspects of measurements are described and machine conditions for standstill tests are also given [6][7][8][9][10].The tests are described in IEC34-4A and ANSI-IEEE Std.115A publications [2][3]. It is very easy to perform in practice.…”
