Resumen
System and method to improve the de-excitation of synchronous machines in dynamic regime. System and method for improving the de-excitation in dynamic regime of synchronous machines, which inserts the discharge resistance (13) during the de-excitation transient by controlling an additional field switch (12). This new system is based on the measurement of the output voltage (14) of the automatic voltage regulator (9). If this voltage is lower than a certain threshold (17), the system is de-energizing. Therefore, the system will insert the discharge resistance (13), by opening the additional field switch (12). Once said transient has finished, the output voltage (14) of the automatic voltage regulator (9) will be greater than another determined threshold (18). In which case the additional field switch (12) will be closed and the machine will continue to operate under normal operating conditions. (Machine-translation by Google Translate, not legally binding)
