Description
Technical field
The present invention relates to be used to control the voltage amplitude of heterogeneous electrical transmission net and/or the induction voltage regulator of phase angle; This electrical transmission net shows the primary side with primary voltage and has the primary side of controlled secondary voltage; This induction voltage regulator is connected between the primary side and primary side of transmission network, comprises the stator with stator winding and stator poles and has the rotor of rotor winding and rotor pole.
The invention still further relates to and utilize induction voltage regulator to control the method for the voltage and the phase angle of high-tension heterogeneous transmission network.
The invention still further relates to and utilize induction voltage regulator that the direction of energy (power flow) of high-tension heterogeneous transmission network is controlled.
Background technology
Control the active power trend in AC (interchange) network according to equation:
U wherein
1And U
2Be respectively the voltage of network transmitting terminal and receiving terminal.Line reactance is X, and δ is the angle between the voltage.
A reason that in network, needs the control direction of energy is in order to use transfer system (network) as much as possible to consuming (load) from producing (generator).This means to use more and have low yield generation generator originally.If unforeseen incident takes place, so just need carry out design to generator about the unoptimizable mode that produces cost in network.Because the controllability in the network, thereby can produce with the low consumption mode.
As everyone knows, can influence the active power trend in the network through following multiple mode:
-reduce or the increase voltage amplitude;
-change reactance through increasing series capacitor;
-use phase-shifting transformer to change angle δ;
-increase shunt voltage and series voltage according to said method, be commonly referred to UPFC, SSSC, FACTS or similar initial;
-use induction voltage regulator.
When through reducing or when increasing voltage amplitude and influencing the active power trend; Since the maximum voltage level that allows (usually ± 5%) be preferably in high-voltage level under operation reducing the situation of the loss in the network, so to reduce or increase voltage amplitude be limited with the control range of change voltage.
When using series capacitor to influence the active power trend, only can reactance be reduced to certain level, and because can not the overcompensation circuit in reality, then can consider line status and apply electric current.
On the other hand, phase shifter can be controlled the direction of energy, and applies any electric current through between its terminal, introducing phase shift.
UPFC (THE UPFC) utilizes power electronic device transferring electric power between the transformer that is connected in parallel and is connected in series.Through suitable control, might under the rated power of device, obtain optional output voltage.The shortcoming of existing UPFC mainly is to be difficult to protect the power electronic device in the series transformer side.Whether also exist really need be in the discussion of the complete controllability aspect amplitude and the phase place two about the site.Some site needs more multivoltage control, and other site needs more perspective control, so that with the optimal way using system.
The induction voltage regulator that is used to control voltage and angle in the very accurate and continuous voltage-controlled laboratory of needs and other place.At present, basically induction voltage regulator being used as the subsection that relates to voltage and power uses.Use field early also is that generator is carried out voltage control, wherein can present the excitation winding on the machine rotors through induction voltage regulator.But the electrification electronic device is as the major part that realizes this purpose now.
Induction voltage regulator is an asynchronous machine, and it does not move as motor, but has fixing rotor, and its rotor direction at an angle rotates with control voltage.
The mechanical movement that this control depends on rotor is connected to another phase place with the stream of specified quantitative from a phase place.The needed electric power of rotor is proportional with the electric power through this rotor.Control rate is low, and needs very big mechanical force to obtain the slow change of output voltage.In induction voltage regulator, voltage and amplitude all change.In this case, output voltage is followed a kind of circulation.The shortcoming of induction voltage regulator is that voltage amplitude also changes when angle δ changes.
According to this method, the direction of energy on the power circuit is controlled through two kinds of different modes basically.
One base part transmits electric power between phase place, another kind of parts only influence the impedance of particular phases.First kind parts comprise phase-shifting transformer, HVDC and UPFC.
Second base part mainly comprises the FACTS and the series capacitor of other kinds.
First kind parts have sizable advantage, owing to it can exceed the AC system around depending on by the ACTIVE CONTROL direction of energy.Second base part depends on other impedances of AC network, and possibly only influence the direction of energy to a certain extent.Can be according to the equipment of first kind parts at the minimum that almost is independent of load condition and the maximum magnitude inner control direction of energy, and can not always satisfy this requirement according to the control appliance of second base part.
At for example " TRANSFORMERS for Single and Multiphase Currents " byGisbert Kapp, London Sir Isaac Pitman&Sons, LTD, 1925 (pp.274-283), document in the basic principle of induction voltage regulator has been described.
Also can from GB 400.100 and GB 549,536, understand induction voltage regulator.
Induction voltage regulator can be single-phase or heterogeneous, but the present invention relates to the polyphase induction voltage regulator, preferably relates to three-phase induction regulator.
The operator scheme of three-phase induction regulator is below described.When hope obtains the continuous rotation of voltage vector, promptly during the continuously changing of voltage phase angle, use induction voltage regulator.Rotor is fixed, but this rotor is set to and can rotate through special angle with respect to stator.Carrying out suitable machinery commentaries on classics through worm gear revolves.When rotor fixedly the time, the direction of the RMF vector of rotor-side depends on the position of rotor with respect to stator.If machine encourages from stator side; Then in this case; There is phase equalization between the voltage of inducting in voltage of in stator winding, inducting and the rotor winding; Wherein the winding phase place of stator and rotor be set to opposite each other, but when rotating certain electrical degree (1 pole span=180 electrical degrees) α on the direction of rotation of rotor at induction flux forward, then the vector corresponding to time-angle is shifted (on phase place, lagging behind) in time.If rotor rotates in the opposite direction, to compare with last situation so, the vector of secondary voltage will have the phase angle of opposite in sign.
The shortcoming of induction voltage regulator is that the possibility of control is restricted to the voltage change that vector reaches, and this changes the phase angle of voltage simultaneously.Because angle rotation produces the change of voltage, this causes the difficulty that circuit and device be connected in parallel and the therefore reactive effect of the circulation of generation.
According to first aspect, the present invention provides a kind of improved induction voltage regulator, is used for controlling the direction of energy in the heterogeneous transmission network of high-voltage alternating.
According to second aspect, the present invention provides a kind of method of utilizing induction voltage regulator to control the voltage and the phase angle of this type of high-tension heterogeneous transmission network.
According to the third aspect, the present invention provides the use to induction voltage regulator, carries out improved control with voltage and phase angle to this type of high-tension heterogeneous transmission network.
