Abstract

A controlling system (20) for controlling together the turbine (2) and the generator (4) of a turbo set (6) has a first controlling element (20a) that generates a first correcting variable (SG) for an excitation controlling member (18) of the generator (4) and a second controlling element (20b) that generates a second correcting variable (ST) for a controlling member (14) of the turbine (2). A real value (Ui) of the mains voltage supplied by a first measurement spot (22) may be supplied to a comparator (30) of the first controlling element (20a). Another real value (Pi), formed by the product of a real value (Ui) supplied by the first measurement spot (22) and of a real value (Ii) supplied by a second measurement spot (24), may be supplied to an additional comparator (40) of the second controlling element (20b). At least one of the measurement spots (22, 24) for recording one of the real values (Ui, Ii) is common to both controlling elements (20a, 20b). This technically simple controlling system (20) allows measurement values to be exchanged. It also allows a reduction in the number of measurement spots and in the number of real values.

Description

Beschreibungdescription
Regeleinrichtung für einen TurbosatzControl device for a turbo set
Die Erfindung bezieht sich auf eine Regeleinrichtung für ei¬ nen eine Turbine und einen Generator umfassenden Turbosatz, der an ein elektrisches Netz angeschlossen ist.The invention relates to a control device for a turbine set comprising a turbine and a generator, which is connected to an electrical network.
Aus der DE-OS 22 21 877 ist eine Anordnung zur Spannungsrege- lung einer Synchronmaschine bekannt, bei der einem Stellglied für den Erregerstrom des Generators eine Stellgröße aufgege¬ ben wird, die aus der Netzspannung und aus einer Laständerun¬ gen charakterisierenden Größe des Netzstromes abgeleitet ist. Mit einer solchen Anordnung kann lediglich der Erregerstrom oder die Generatorspannung und somit die Blindleistung eines Turbosatzes eingestellt werden.From DE-OS 22 21 877 an arrangement for voltage regulation of a synchronous machine is known, in which an actuating variable is given to an actuator for the excitation current of the generator, which is derived from the mains voltage and from a variable of the mains current that characterizes load changes is. With such an arrangement, only the excitation current or the generator voltage and thus the reactive power of a turbo set can be set.
Aus der DE-PS 28 55 404 ist eine Einrichtung zur Leistungsre¬ gelung für einen Turbosatz bekannt, bei der die pro Zeitein- heit in die Turbine eintretende Menge des Arbeitsmittels - z.B. Dampf bei einer Dampfturbine - eingestellt wird. Mit ei¬ ner derartigen Einrichtung wird allerdings nur die Wirklei¬ stung und/oder die Drehzahl des Wellenstranges des Turbosat¬ zes geregelt.From DE-PS 28 55 404 a device for power control for a turbo set is known in which the amount of working fluid entering the turbine per unit of time - e.g. Steam in a steam turbine - is set. With such a device, however, only the active power and / or the speed of the shaft assembly of the turboset is regulated.
Für eine Regelung sowohl der Wirkleistung des Turbosatzes als auch der Generatorspannung und damit der Blindleistung der aus Turbosatz und elektrischem Netz gebildeten Regelstrecke ist ein hoher regelungstechnischer Aufwand erforderlich, zu- mal für die voneinander getrennten und voneinander unabhängig arbeitenden Regeleinrichtungen eine Vielzahl von Meßgrößen und/oder Istwerten erfaßt werden muß.To control both the active power of the turbo set and the generator voltage and thus the reactive power of the control section formed from the turbo set and the electrical network, a high level of control expenditure is required, in particular for the separate and independently operating control devices, a large number of measured variables and / or Actual values must be recorded.
Der Erfindung liegt die Aufgabe zugrunde, eine für einen Tur- bosatz bestimmte Regeleinrichtung mit geringem regelungstech¬ nischem Aufwand anzugeben. Diese Aufgabe wird erfindungsgemäß gelöst durch ein erstes Regelelement zur Bildung einer ersten Stellgröße für ein Er¬ regerstellglied des Generators und ein zweites Regelelement zur Bildung einer zweiten Stellgröße für ein Stellglied der Turbine, wobei einem Vergleichsglied des ersten Regelelements ein von einer ersten Meßstelle abgegebener Istwert der Netz¬ spannung aufgebbar ist, wobei einem weiteren Vergleichsglied des zweiten Regelelements ein weiterer Istwert aufgebbar ist, der aus dem Produkt eines von der ersten Meßstelle und eines von einer zweiten Meßstelle abgegebenen Istwertes gebildet ist, und wobei beiden Regelelementen mindestens eine der Meßstellen zur Aufnahme eines der Istwerte gemeinsam ist.The invention is based on the object of specifying a control device intended for a turbo set with little outlay in terms of control technology. This object is achieved according to the invention by a first control element for forming a first manipulated variable for an exciter actuator of the generator and a second control element for forming a second manipulated variable for an actuator of the turbine, with a comparison element of the first control element having an actual value given by a first measuring point Mains voltage can be applied, with a further comparison element of the second control element being able to apply a further actual value which is formed from the product of an actual value given by the first measuring point and a second measuring point, and wherein both regulating elements have at least one of the measuring points for receiving one the actual values is common.
In zweckmäßiger Ausgestaltung sind die erste und die zweite Meßstelle den Regelelementen gemeinsam, wobei als die erste Meßstelle mindestens ein mit dem Netz gekoppelter Spannungs¬ wandler und als die zweite Meßstelle mindestens ein mit dem Netz gekoppelter Stromwandler vorgesehen sind.In an expedient embodiment, the first and the second measuring point are common to the control elements, at least one voltage converter coupled to the network being provided as the first measuring point and at least one current converter being coupled to the network as the second measuring point.
Die mit der Erfindung erzielten Vorteile bestehen insbeson¬ dere darin, daß durch eine der Turbine und dem Generator ge¬ meinsame Regeleinrichtung eine Einsparung von bereitzustel¬ lenden Istwerten erreicht wird, und daß zwischen den beiden Regelelementen ein Austausch von Meßgrößen möglich ist. Da- durch können die Turbine und der Generator nicht nur vonein¬ ander getrennt geregelt werden, sondern es kann auch bei Soll- und/oder Istwertänderungen in einfacher Weise gleich¬ zeitig sowohl auf den Generator als auch auf die Turbine ein¬ gewirkt werden. Dadurch wird eine besonders gute Regeldynamik erzielt.The advantages achieved by the invention are, in particular, that a saving of actual values to be provided is achieved by means of a control device common to the turbine and the generator, and that an exchange of measured variables is possible between the two control elements. As a result, the turbine and the generator can not only be regulated separately from one another, but it is also possible in a simple manner to act both on the generator and on the turbine in the event of setpoint and / or actual value changes. This results in particularly good control dynamics.
Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung näher erläutert. Darin zeigt die Figur eine gemein¬ same Regeleinrichtung für eine Turbine und einen Generator eines Turbosatzes. Die Turbine 2 und der Generator 4 des Turbosatzes 6 sitzen auf einer gemeinsamen Welle 8, über die der Generator 4 von der Turbine 2 angetrieben wird. Der Generator 4 speist über eine Netzleitung 10 in ein dreiphasiges elektrisches Netz 12 ein. Die Turbine 2 kann eine Gas- oder eine Dampfturbine sein.An embodiment of the invention is explained in more detail with reference to a drawing. The figure shows a common control device for a turbine and a generator of a turboset. The turbine 2 and the generator 4 of the turboset 6 sit on a common shaft 8, via which the generator 4 is driven by the turbine 2. The generator 4 feeds into a three-phase electrical network 12 via a power line 10. The turbine 2 can be a gas or a steam turbine.
Zum Einstellen der Menge des in die Turbine 2 einströmenden Arbeitsmediums a ist ein Turbinenstellglied 14 in Form eines Ventils oder einer Anzahl von Ventilen vorgesehen.A turbine actuator 14 in the form of a valve or a number of valves is provided for adjusting the amount of the working medium a flowing into the turbine 2.
Die Erregerwicklung 16 des Generators 4 wird über ein steuer¬ bares Erregerstellglied 18, z.B. in Form eines Thyristor-Sat¬ zes oder eines Transistorstellers gespeist. Das Erregerstell- glied 18 bildet den für die Erregung erforderlichen variablen Gleichstrom oder Erregerstrom Ig.The field winding 16 of the generator 4 is controlled via a controllable field actuator 18, e.g. fed in the form of a thyristor set or a transistor actuator. The excitation actuator 18 forms the variable direct current or excitation current Ig required for excitation.
Die dem Generator 4 und der Turbine 2 gemeinsame Regelein¬ richtung 20 weist ein erstes Regelelement 20a für den Genera- tor 4 und ein zweites Regelelement 20b für die Turbine 2 auf. Der Regeleinrichtung 20 werden als Eingangsgrößen die Istwer¬ te Ui, l£ der Netzspannung bzw. und des Netzstromes zuge¬ führt, die in beiden Regelele enten 20a, 20b gemeinsamen, mit der Netzleitung 10 verbundenen Meßstellen 22 bzw. 24 abge- griffen werden. Dabei sind die Meßstellen 22 und 24 minde¬ stens ein Spannungs- und mindestens ein Stromwandler, wobei die Spannung bzw. der Strom einzelner oder aller Phasen des dreiphasigen Netzes 12 gemessen wird. Außerdem wird der Re¬ geleinrichtung 20 der Istwert Igi des an einer Meßstelle 26 erfaßten Erregerstroms Ig zugeführt. Von der Regeleinrichtung 20 abgegebene Stell- oder Steuergrößen SG und ST werden dem Erregerstellglied 18 bzw. dem Turbinenstellglied 14 aufgege¬ ben.The control device 20 common to the generator 4 and the turbine 2 has a first control element 20a for the generator 4 and a second control element 20b for the turbine 2. The control device 20 is supplied with the actual values Ui, l £ of the mains voltage and / or the mains current, which are tapped in both control units 20a, 20b, common measuring points 22 and 24 connected to the mains line 10. The measuring points 22 and 24 are at least one voltage and at least one current transformer, the voltage or the current of individual or all phases of the three-phase network 12 being measured. In addition, the control device 20 is supplied with the actual value Igi of the excitation current Ig detected at a measuring point 26. Actuating or control variables SG and ST output by the control device 20 are applied to the exciter actuator 18 and the turbine actuator 14, respectively.
Die erste Stellgröße SG für das Erregerstellglied 18 wird in dem ersten Regelelement 20a gebildet. Dazu wird einem Regler, insbesondere einem PI-Regler 28, als Eingangsgröße ein in ei- nem Vergleichsglied 30 gebildeter Vergleichswert ΔU ui ~ us aufgegeben, der aus dem Istwert ü*i der Netzspannung und einem von einem Sollwertgeber 32 vorgegebenen Sollwert Uε gebildet ist. Die den Sollwert Igs für den Erregerstrom Ig bildende Ausgangsgröße des PI-Reglers 28 wird in einem Ver¬ gleichsglied 34 mit dem Istwert Igi des an der Meßstelle 26 erfaßten Erregerstroms g verglichen. Aus dem dabei gebildeten Vergleichswert Δlg = Igi - IgS wird mittels eines weiteren PI-Reglers 36 die Stellgröße SG für das Erregerstellglied 18 abgeleitet.The first manipulated variable SG for the exciter actuator 18 is formed in the first control element 20a. For this purpose, a controller, in particular a PI controller 28, is fed as an input variable into a A comparison value ΔU u i ~ u s formed by a comparison element 30, which is formed from the actual value u * i of the mains voltage and a setpoint value U ε specified by a setpoint generator 32, is given up. The output variable of the PI controller 28 forming the setpoint I gs for the excitation current Ig is compared in a comparator 34 with the actual value Igi of the excitation current g detected at the measuring point 26. The manipulated variable SG for the exciter actuator 18 is derived from the comparison value Δlg = Igi - Ig S formed in this way by means of a further PI controller 36.
Die zweite Stellgröße ST für das Turbinenstellglied 14 wird in dem zweiten Regelelement 20b gebildet. Dabei wird zunächst aus demselben Istwert u*i der Netzspannung und dem Istwert li des Netzstroms mittels eines Multiplizierers 38 ein Lei¬ stungs-Istwert Pi gebildet. Der in einem weiteren Vergleichs¬ glied 40 aus diesem Leistungs-Istwert Pi und einem von einem Sollwertgeber 42 vorgegebenen Leistungs-Sollwert Ps erstellte Vergleichswert ΔP = Pi - Ps wird als Eingangsgröße einem PI- Regler 44 zugeführt, der daraus die Stellgröße ST für das Turbinenstellglied 14 ableitet.The second manipulated variable ST for the turbine actuator 14 is formed in the second control element 20b. Initially, an actual power value Pi is formed from the same actual value u * i of the mains voltage and the actual value li of the mains current by means of a multiplier 38. The comparison value ΔP = Pi - P s created in a further comparison element 40 from this actual power value Pi and a power setpoint value P s predetermined by a setpoint generator 42 is fed as an input variable to a PI controller 44, which uses it to control variable ST for derives the turbine actuator 14.
Die dem Generator 4 und der Turbine 2 gemeinsame Regelein¬ richtung 20 ermöglicht mit geringem regelungstechnischem Auf- wand eine gute und sichere Regelung des Turbosatzes 6, insbe¬ sondere aufgrund des Einsatzes von beiden Regelelementen 20a und 20b gemeinsamen Meßstellen 22, 24. Zur Berücksichtigung weiterer Einflußgrößen können der Regeleinrichtung 20 weitere gemeinsame Sollwert-Führungsgrößen SW und Istwert-Eingangs- großen IW, z.B. der Turbinendrehzahl oder der Generatorfre¬ quenz, zugeführt werden; dies ist durch die Pfeile 46 bzw. 48 angedeutet. The control device 20 common to the generator 4 and the turbine 2 enables good and safe control of the turboset 6 with little control outlay, in particular due to the use of measuring points 22, 24 common to both control elements 20a and 20b Influencing variables can control unit 20 have further common setpoint reference variables SW and actual value input variables IW, for example the turbine speed or the generator frequency are supplied; this is indicated by the arrows 46 and 48.
