Description
Verfahren zur Regelung des Leistungsüberganges zwischen zwei oder mehreren Wechselstromkraftwerken Es liegt vielfach die Aufgabe vor, den Übergang der Leistung zwischen zwei oder mehreren Wechselstromkraftwerken bzw. Energieverteilungsnetzen auf einen bestimmten Betrag rinzuregeln.Procedure for regulating the transfer of services between two or several alternating current power plants It is often the task of the transition the power between two or more AC power plants or energy distribution networks to regulate to a certain amount.
Gemäß der Erfindung wird zu -diesem Zweck die Lage der Spannungsvektoren an verschiedenen Punkten der betreffenden Kupplungsleitung, z. B. am Anfang und am Ende der Kuppelleitung, miteinander verglichen und in Abhängigkeit von der Größe der Winkel-Abweichung die Energiezufuhr zu den Kraftmaschinen des .einen bzw. des anderen Netzes geregelt. Man kannbeispielsweise die Energiezufuhr zu den Kraftwerken derart beeinflussen, daß der Winkel zwischen den Spannungsvektoren an den beiden Meßpunkten konstant bleibt. In diesem Fall geht praktisch eine konstante Leistung zwischen den Netzen über. Da die Verdrehung der Spannungsvektoren bei Lastschwankungen sofort einsetzt, so.kann man auf diese Weise eine sehr rasch wirkende Regelung erzielen. Die Spannungsvektoren an den Enden der Küppelleitungen können 'auch gleichzeitig als.. Normalvektoren für die Regelung der Strömerzeuger benutzt werden, die an das betreffende Ende der' Übertragungsleitung angeschlossen sind. Maxi kann nämlich mit Hilfe dieses Normalspannungsvektors die Leistung auf die einzelnen Generatoren oder Unterwerke des Netzes gleichmäßig verteilen, wenn man die Winkellage zwischen dem Normalspannungsvektor und dem Vektor der EMK der einzelnen Generatoren mißt und in Abhängigkeit von diesem Winkel die Energiezufuhr verstellt. Derartige Einrichtungen sind an sich bekannt und vorgeschlagen worden, um zwei nicht miteinander gekuppelte Netze derart in Synchronismus zu halten, daß .eine Kupplung jederzeit möglich ist.According to the invention, the position of the voltage vectors is used for this purpose at different points of the coupling line in question, e.g. B. at the beginning and at the end of the coupling line, compared with each other and depending on the size the angle deviation determines the energy supply to the prime movers of the one or the other other network regulated. One can, for example, the energy supply to the power plants affect such that the angle between the voltage vectors at the two Measuring points remains constant. In this case, the output is practically constant between the networks over. Because the twisting of the voltage vectors with load fluctuations starts immediately, so you can achieve a very quickly effective control in this way. The voltage vectors at the ends of the tubing lines can also be simultaneously as .. normal vectors are used for the regulation of the flow generators, which are connected to the relevant end of the 'transmission line are connected. Because Maxi can with the help of this normal voltage vector the power to the individual generators or distribute substations of the network evenly, if one considers the angular position between the normal voltage vector and the vector of the EMF of the individual generators and adjusts the energy supply as a function of this angle. Such facilities are known per se and have been proposed to be two uncoupled To keep networks in synchronism in such a way that. A coupling is possible at any time.
Zwecks Vergleichs der Lage der Spannungsvektoren können die zu vergleichenden Spannungen beispielsweise mit Hilfe von Leitungen nach dem Meßort, der z. B. an der einen Meßstelle liegt, übertragen werden. Die durch die Übertragung etwa auftretenden Phasenverschiebungen. müssen beim Aufbau det Regelapparatur berücksichtigt werden. Man kann die Spannung nach dem Meßort aber auch mit Hilfe von Hochfrequenz- übertragen. Zu diesem Zweck genügt es, einen Hochfrequenzsender im .Takte der Spannung an der Meßstelle zu modulieren und in üblicher Weise die am Empfangsort eintreffenden Hochfrequenzwellen gleichzurichten. Die Hochfrequenzübertragung ist besonders dann vorteilhaft; wenn der Abstand zwischen den Meßstellen groß ist und bei der Übertragung der Spannungen erhebliche Phasenverschiebungen zu befürchten sind.For the purpose of comparing the position of the voltage vectors, the Voltages, for example with the help of lines after the measurement location, the z. B. at which is a measuring point. The ones that may occur as a result of the transfer Phase shifts. must be taken into account when setting up the control system. The voltage can also be transmitted to the measuring location with the help of high frequency. For this purpose, it is sufficient to have a high-frequency transmitter in .Takt the voltage on the To modulate the measuring point and in the usual way the high-frequency waves arriving at the receiving location rectify. The high-frequency transmission is particularly advantageous then; if the distance between the measuring points is great and when transferring of the voltages, considerable phase shifts are to be feared.
