5. embodiment
It in Fig. 1 frame of broken lines the composition frame chart of high voltage direct current electricity generation system integrated generator controller of the present invention.As shown in Figure 1, the exciter output signal is controlled its break-make by field application relay, the output signal U of the output signal of field application relay after the rectification circuit rectification
PMGSend into the voltage regulator main circuit that links to each other with main generator excitation winding F, digital signal processor DSP and peripheral circuit are connected in the voltage regulator main circuit through the digital voltage regulation interface circuit.Two current detection signals of the current detection sensor CT1 of detection generator output load current size and the current detection sensor CT2 of detection system differential current are input to the digital voltage regulation interface circuit respectively.Digital signal processor DSP is connected in solid-state generators circuit breaker main circuit by the solid circuit breaker interface circuit.
Several major technique divisions of technique scheme of the present invention are as follows:
A. generator circuit breaker adopts the technical scheme of all solid state switch, is referred to as solid-state generators circuit breaker (Solid State Generator Breaker is called for short SSGB).Utilize a plurality of field effect transistor MOSFET to compose in parallel all solid state switch, can improve switch power and reduce the switch conduction loss.Substitute the generator circuit breaker of hybrid power controller or other types with solid-state switch, solved the electric arc problem of mechanical contact-type switch effectively, and its switching speed is much higher than the responsiveness of contact switch mainly by the turn-on and turn-off speed decision of field effect transistor.
Solid-state generators circuit breaker main circuit of the present invention as shown in Figure 2.Constitute by 10 field effect transistor MOSFET parallel connection.Vibrationproof resistance of serial connection on each field effect transistor MOSFET grid lead wire adopts grid indirect coupling mode, is beneficial to the dynamic current equalizing of parallel field effect pipe MOSFET.The drain electrode of 10 field effect transistor MOSFET and source electrode are connected in parallel by wide copper bar respectively, can effectively reduce parameters such as line impedance and stray inductance.The copper bar both sides respectively and meet a noninductive capacitor C 1 of high frequency, C2, to absorb the due to voltage spikes that inductive element causes in the switching tube shutdown moment circuit.
A plurality of field effect transistor MOSFET parallel operations, drive circuit need have enough driving forces.The solid-state generators circuit breaker SSGB control signal that digital signal processor DSP sends is divided into two-way (as shown in Figures 2 and 3) after power amplification, respectively through input high speed field effect transistor MOSFET chip for driving UCC27321 behind the optical coupling isolation circuit, this novel chip for driving output adopts the unique bipolar transistor totem and the parallel-connection structure of double-field effect pipe MOSFET totem, and the peak drive current of 9A can be provided in time hundreds of nanosecond.The output of each chip for driving UCC27321 drives 5 field effect transistor MOSFET.
In addition; for preventing solid-state generators circuit breaker SSGB off period; still have drain voltage on the generator busbar, an earth leakage circuit-breaker pipe (being made of field effect transistor MOSFET pipe) is set, its control signal also produces (as Fig. 4) by digital signal processor DSP.Earth leakage protective field effect transistor MOSFET and load are connected in parallel, and when solid-state generators circuit breaker SSGB opened, it must be in cut-off state, otherwise the generator output dc voltage will be by short circuit.Thereby, we are provided with latching relation between solid-state generators circuit breaker SSGB drive signal and earth leakage circuit-breaker drive signal, when solid-state generators circuit breaker SSGB drive signal is " height " (being solid-state generators circuit breaker SSGB conducting), the earth leakage circuit-breaker control signal no matter digital signal processor DSP sends is " height " or " low ", behind logical circuit and power amplification circuit, the drive signal of earth leakage circuit-breaker is " low ", and earth leakage circuit-breaker ends; When solid-state generators circuit breaker SSGB drive signal was " low " (being that solid-state generators circuit breaker SSGB turn-offs), the earth leakage circuit-breaker control signal that the drive signal of earth leakage circuit-breaker is sent by digital signal processor DSP was normally controlled.Solid-state generators circuit breaker SSGB off period; voltage swing on the digital signal processor DSP chip detection generator busbar; if drain voltage surpasses setting, then digital signal processor DSP sends the earth leakage circuit-breaker pipe and opens signal, thereby drain voltage is discharged by earth leakage circuit-breaker.
B. Digital Voltage Regulator has functions such as digital voltage regulation, load current limit, the excessive protection of exciting current, is core CPU with the high speed digital signal processor dsp chip.
Generator output voltage behind the modulate circuit, is carried out unscented transformation to it, is become digital quantity signal by mould/number conversion module after testing.According to this digital quantity, utilize suitable control algolithm to produce pulse width modulated wave PWM, after power amplification, control the on off state of power tube in the energized circuit again.Control algolithm is followed the tracks of the variation of output voltage, changes the duty ratio of pulse width modulated wave PWM, thereby regulates the size of exciting current, realizes the purpose of regulated output voltage.
Load current limit realizes by the maximum of restriction exciter current of generator.Relation is determined by the regulating characteristics of motor between exciting current and generator output current, variable-speed generator has different regulating characteristicss corresponding to different working speeds, so limits value for same output current, corresponding exciting current limits value is different, exciting current during the slow-speed of revolution is big, exciting current is little during high rotating speed, so should select different exciting current limits values according to different rotating speeds.
Exciter current of generator becomes digital quantity signal after passing through current sensor, detection modulate circuit and mould/number conversion, and digital signal processor DSP regularly detects the exciting current size.In case exciting current is excessive, digital signal processor DSP blocks PWM output, and the dutyfactor value of promptly putting output PWM is 0, thereby the switching tube in the excitation main circuit is ended.Simultaneously, digital signal processor DSP sends field application relay GCR cut-off signals, disconnects field application relay GCR to cut off the generator excitation source.For variable-speed generator, should select different exciting current protection values according to different rotating speeds equally.
The digital voltage regulator main circuit is used to provide the energized circuit of generator excitation winding as shown in Figure 5.Excitation source is obtained after full-bridge rectification, filtering by the three-phase alternating current output of permanent magnet excitation machine.Two power switch pipe Q1, Q2 are arranged in the main circuit, and Q1 is a main switch, and Q2 is contrary magnetic tube.Two sustained diode 7, D8 provide the energy bleed-off circuit for excitation winding.Generator is prominent to unload load or institute's load of unloading hour, and contrary magnetic tube Q2 is in conducting state always, and main switch Q1 is the pulse-width modulation working method.Main switch Q1 conducting, exciting current i
FIncrease, main switch Q1 turn-offs, i
FReduce, because of switching frequency higher, i when main switch Q1 opens and turn-offs
FVariable quantity all very little, so can not cause the pulsation of output voltage.Generally speaking, as long as the main switch duty ratio is less, during the electricity generation system shock load, the output voltage transient response meets the demands easily.Dash forward when unloading load, the circuit structure of free afterflow was difficult to satisfy the dynamic property requirement of voltage regulator when the switching tube traditional as if employing turn-offed.Adopt main circuit structure as shown in Figure 5, dash forward when unloading load, generator voltage raises, and main switch Q1, contrary magnetic tube Q2 are turn-offed in the CPU control of digital voltage regulator simultaneously, and exciting current is through sustained diode 7 and D8 afterflow, because voltage U on the filter capacitor
PMGEffect, the exciting current decay is accelerated, thereby generator output voltage is also descended rapidly.Contrary magnetic tube Q2 only just disconnects after generator voltage is greater than rated value, and it is promptly closed that voltage recovers the back.
The digital voltage regulation interface circuit comprises that analog quantity detects modulate circuit, digital controlled signal power amplification circuit.The analog quantity that needs to detect conditioning has: generator output (point of adjustment) voltage, generator output current, differential current, exciting current, generator speed, field power supply voltage etc.Digital controlled signal has: field application relay control signal, main switch control pwm signal, contrary magnetic tube control signal etc.
Point of adjustment voltage detecting circuit such as Fig. 6.Resistance R 11 and R12 exchange node voltage and carry out dividing potential drop, amplifier U1 (LM158) and linear optical coupling U2 (HCNR201) constitute the linearity test circuit and isolate, output voltage passes through the filter circuit of voltage follower U3 and resistance R 16 and capacitor C 8 compositions again, finally input to the inner A/D converter of TMS320F240 type digital signal processor DSP, voltage-stabiliser tube Z1 is in order to prevent the excessive damage A/D converter of voltage conditioned signal.
Power amplification circuit such as Fig. 7 of main switch control pwm signal.U4 for realize " with " the high-speed driving switch S N75451 of logic.When pwm signal was " height " level, driving switch SN75451 was output as " height ", NPN transistor Q14 conducting, and optocoupler U5 (HCPL3120) is output as " low ", and promptly main switch MOSFET pipe drive signal is " low ", and switching tube ends; Otherwise drive signal is " height ", the switching tube conducting.
Field application relay control circuit such as Fig. 8.Optocoupler U6 (TIL117) realizes the isolation of control signal and power circuit.U7A (MC1413B) is in order to realize the power amplification to control signal, and its output drives auxiliary relay K1, in two groups of contacts of K1, and the pumping signal of one group of output field application relay coil, the status signal of another group output field application relay.D10 is the fly-wheel diode of auxiliary relay coil.
C. load current detecting sensor CT1 is used to detect the load current size.Current sensor CT2 detection system differential current, two power lines of electricity generation system direct current output pass CT2 simultaneously.Under the normal condition, the size of current in two power lines equates that direction is opposite, thereby differential current is zero; When load-side generation shorted to earth; current direction in two power lines is identical, and differential current significantly increases, if digital signal processor DSP detects differential current and is worth greater than protection; then send the differential protection signal, turn-off switching tube and field application relay in the excitation main circuit.
Therefore, there is direct electrical connection between current measuring element, solid-state generators circuit breaker and the engine controller.They are comprehensively advanced in the casing, constitute integrated generator controller.Like this, the high voltage direct current electricity generation system is reduced to 2 parts (high voltage direct current brushless generator and integrated generator controller) by 4 field-replaceable units.Thereby avoided external signal connecting line complicated between each parts of system, made system configuration obtain simplifying, improved system reliability and maintainability effectively.
Beneficial effect:
Proposition is applied to the solid-state switch technology in the main-generator breaker, has thoroughly solved the electric arc problem of generator circuit breaker in the aircraft high-voltage DC power supply, and can significantly improve the switching response speed of generator circuit breaker.Employing is easy to realize advanced control algolithm based on the digital voltage regulation technology of DSP, and it is easy to adjust Control Parameter, is applied to will improve in the high voltage direct current electricity generation system the dynamic and static quality of output voltage of high-voltage DC power supply.Propose integrated generator controller version, reduced the functional part number of electricity generation system, thus the external signal connecting line of complexity between each parts of minimizing system, and simplied system structure has improved system reliability and maintainability effectively.These technology are significant to China's research and development aircraft high voltage direct current electricity generation system.
