Description
Einrichtung zur Regelung der Leistungsbeteiligung mehrerer auf das gleiche Netz arbeitender Synchronmaschinen Gegenstand des Patents 675 375 ist eine Einrichtung zur Regelung der Leistungsbeteiligung mehrerer auf das gleiche Netz arbeitender Synchronmaschinen mit beliebiger Antriebsmaschine, bei denen die Leistungsbieteiligung gemäß einer frei einstellbaren Leistungskennlinie geregelt wird unter Heranziehung des inneren Spannungsabfalls zwischen innerer Maschinen-EMK und Klemmenspännung. Gemäß diesem Patent wird diese Kennlmk fahrplanmäßig dadurch beeinflußt, daß die zur Regelung erforderliche Meßgröße gemäß dem Spannungsabfall E's in. einer Widerstandsnachbildung der Maschinenwiderstände gebildet wird, welche von dem Laststrom oder einem diesem proportionalen Strom durchflossen ist. Diese Nachbildungswiderstände sind zusätzlich entsprechend der gewünschten Leistungstrennlinie regelb,ax. Hierdurch wird reicht, daß die Kennlinie der Maschine -den jeweiligen Netzverhältnissien selbsttätig angepaßt wird, ohne daß an der Maschine eine Regelung vorgenommen werden. muß, z. B. Erregungsänderung oder Verstellung der räumlichen Lage des Ständers. Es- wird daher die Phasenlage der Klemmenspannung mit derjenigen des Spannungsäbfalles, an Widerständen verglichen, die den inneren Spannungsabfall der Maschinen wiedergeben.Facility for regulating the participation of several on the same network of synchronous machines working the subject of patent 675,375 is a Device for regulating the participation of several services on the same network working synchronous machines with any drive machine in which the power sharing is regulated according to a freely adjustable performance curve using the internal voltage drop between internal machine EMF and terminal voltage. According to this patent, this characteristic is scheduled to be influenced by the fact that the Measured variable required for regulation according to the voltage drop E's in a resistor simulation the machine resistances is formed, which is caused by the load current or one of this proportional current flowing through it. These replication resistors are additional according to the desired power dividing line regulb, ax. This is enough that the characteristic of the machine -adapted automatically to the respective network conditions without any regulation being carried out on the machine. must, e.g. B. Change of excitation or adjustment of the spatial position of the stand. It is therefore the phase position the terminal voltage with that of the voltage drop compared at resistors, which reflect the internal voltage drop of the machines.
Gemäß der Erfindung wird nun diese Einrichtung dadurch verbessert, daß die Leistungsregelung von der Phasenverschiebung zwischen der Maschinenklemmenspannung bei Belastung und der Leerlaufspannung an irgendeinem fiktiven Punkt des Netzes dadurch abhängig gemacht wird, daß die Netznachbildung in Regelwüderständen erfolgt,. die den inneren Widerständen der miteinander parallelarbeitenden Maschinen und zusätzlich den Netzwiderständen bis zu demjenigen Punkt, auf den die Regelung bezogen ist, entsprechen.According to the invention, this device is now improved by that the power control of the phase shift between the machine terminal voltage at load and open circuit voltage at any fictitious point in the network is made dependent on the fact that the network simulation takes place in regular wilderness. the internal resistances of the machines working in parallel with each other and additionally the network resistances up to the point to which the regulation is based, correspond.
Man ist hierdurch, ,in der Lage, so zu regeln, als ob man die Leistung an diesem Punkt beeinflussen wollte, ohne daß man an diesen Netzpunkten, an dis man die Maschinenklemmen verlegt gedacht hat, wirkliche Messungen mit den dazu notwendigen Meßeinrichtungen und Fernübertragungsgliedern anzustellen braucht.As a result, you are able to regulate the performance as if you were performing wanted to influence at this point without having to dis the machine terminals were thought to have been misplaced, real measurements with the necessary Measuring devices and need to employ remote links.
Man kann durch entsprechende Ausgestaltung der Nachbildungswiderstände jeden beliebigen Netzzustand vortäuschen, wobei die.J.e Widerstände durch ein Netzblindschema mit entsprechender Leitungsnachbildung zusätzlich so abgeändert werden, daß der Nachbildungswiderstand dem jeweiligen wirklichen oder gedachten Netzzustand entspricht.You can design the simulation resistors accordingly simulate any network state, whereby the.J.e resistances by means of a network blind scheme can also be modified with a corresponding line simulation so that the Replication resistance corresponds to the respective real or imaginary network state.
Die cos y-Kompension kann sich dabei gemäß dem Hauptpatent nur auf denjenigen Teil des Nachbildungswiderstandes beschränken, der dem inneren. Widerstand der jeweils parallel arbeitenden Synchronmaschinen entspricht.According to the main patent, the cos y compensation can only refer to limit that part of the replication resistance which is the inner. resistance corresponds to the synchronous machines working in parallel.
Durch eine solche Regelung kann man eine Leitvektorregelung ersetzen, ohne deren Starrheit in Kauf nehmen zu müssen. Auch besteht die Möglichkeit, daß bei Netzbetrieben mit Lastverteilungsstellen von diesen aus entsprechend der gewollten Leistungsverteilung unmittelbar mit bekannten Mitteln auf die Nachbildungswiderstände'eingewirkt wird, wodurch sich eine einfache und stabile Regelung ergibt.A control vector control can be replaced by such a control, without having to accept their rigidity. There is also the possibility that in the case of network operations with load distribution points from these according to the desired Power distribution acted directly on the replication resistors by known means which results in a simple and stable control.
Auch die Regelung der Übergabeleistung an irgendeiner Kuppelstelle kann mit der Einrichtung nach der Erfindung bewerkstelligt werden.Also the regulation of the transfer power at any coupling point can be accomplished with the device according to the invention.
