Description

Technical Field

[0001] The present invention relates to, but is not limited to, the technical field of aviation power systems, and in particular to a device and method for synchronous verification of physical objects and real-time simulation of aviation power systems. Background Art

[0002] At present, the test methods of aviation power systems can be basically divided into three categories: full digital simulation verification, semi-physical simulation verification, and full physical verification. Usually, full digital simulation verification is mainly used in the system development and scheme design stages. Due to the large scale of aviation power systems and the involvement of many professional disciplines, system-level full digital simulation verification does not have full functional performance verification and usually focuses on system architecture-level verification. Semi-physical simulation verification is generally divided into two categories: HIL (Hardware in the Loop) and RCP (Rapid Control Prototyping). HIL semi-physical simulation is mainly used to verify controller functions, and RCP semi-physical simulation is mainly used to verify control strategies. Full physical verification is usually used for the final functional performance verification of the system.

[0092] The embodiment of the present invention provides a physical and real-time simulation synchronous verification device and method for an aviation power system. In the physical and real-time simulation synchronous verification device, the top-level control module interacts with the power distribution measurement and control module, the real-time simulator 1, and the real-time simulator 2 respectively through information. The top-level control module sends the same first communication information to the power distribution measurement and control module or / and the real-time simulator 2 to provide basic conditions for physical or / and real-time simulation. The top-level control module sends second communication information to the real-time simulator 1 to generate digital instructions through the real-time simulator 1 and transmit them to the power distribution measurement and control module or / and the real-time simulator 2 respectively; accordingly, on the one hand, the power distribution measurement and control module parses the received first communication information and digital instructions and sends them to the physical integration verification module for physical verification test, and transmits the physical operation results back to the real-time simulator 1 through the power distribution measurement and control module; on the other hand, the real-time simulator 2 performs real-time simulation based on the received first communication information and digital instructions, and transmits the real-time simulation results back to the real-time simulator 1.

[0093] Compared to the three existing test methods for aviation power systems, each method can only test different stages of the aviation power system and has certain limitations. It is difficult for any one test method to test and verify the entire stage of the aviation power system design. The above-mentioned device provided by the embodiment of the present invention can not only perform physical integration verification and real-time simulation separately, but also perform physical integration verification and real-time simulation simultaneously. That is, the device provided by the embodiment of the present invention can be used for system integration verification of aviation power systems, which has the advantages of shortening the system design and verification cycle and reducing development costs.

[0094] The following describes the architecture of the aviation power system used as a verification object in the embodiment of the present invention. Figure 3 Figure 2 shows a schematic diagram of the system architecture of a dual-channel high-voltage DC aviation power system according to an embodiment of the present invention. The aviation power system comprises a dual-redundant 270V high-voltage DC generator subsystem, a 270V distribution box, a 270V / 28V DC converter, a 28V distribution box, a 28V battery, a 28V ground power supply, and a system control unit. Figure 4 for Figure 3 The control logic diagram of the contactor K3 in the aviation power system provided by the embodiment shown is as follows: Figure 5 for Figure 4 The embodiment shown provides a schematic diagram of the control scheme of the contactor K3; Figure 6 for Figure 3The control logic diagram of the contactor K9 in the aviation power system provided by the embodiment shown is as follows: Figure 7 for Figure 6 The illustrated embodiment provides a schematic diagram of a control scheme for the contactor K9; Figure 8 for Figure 3 A schematic diagram of a system control and status monitoring solution for an aviation power system provided by the illustrated embodiment; Figure 9 for Figure 3 The embodiment shown is a schematic diagram of a communication solution for an aviation power system. Figure 3 The system features are detailed as follows:

[0095] (1) Redundant busbar power supply. When the 270V high-voltage DC generating subsystems 1 and 2 are supplying power normally, the contactor K3 is disconnected. When one of the 270V high-voltage DC generating subsystems cannot supply power to the corresponding busbar, the contactor K3 is closed and the other busbar supplies power to the power-off busbar. The power supply control logic of the contactor K3 is as follows: Figure 4 As shown, the control scheme is as Figure 5 Similarly, when 270V / 28V DC converters 1 and 2 are supplying power normally, contactor K9 is disconnected. When one of the 270V / 28V DC converters cannot supply power to the corresponding bus, contactor K9 is closed and the other bus supplies power to the power-off bus. The power supply control logic of contactor K3 is as follows: Figure 6 As shown, the control scheme is as Figure 7 As shown in the figure, 28V DC buses 3 and 4 are powered by the 28V ground power supply when the system is operating on the ground. After the system starts, 28V DC buses 3 and 4 are powered via 28V DC buses 1 and 2, respectively. The 28V ground power supply is disconnected from the grid, closing contactor K13 and ensuring uninterrupted power supply to 28V DC buses 3 and 4. Diodes V1, V2, V3, and V4 prevent backflow.

[0096] (2) System control and status monitoring. System control and status monitoring solutions such as Figure 8 As shown in the figure, the real-time simulator is the core of system control and status monitoring, while the power distribution measurement and control platform serves as the middle layer. The two 270V and two 28V distribution management centers are the controlled and monitored objects. Control commands for each contactor in the distribution system originate from the real-time simulator and are conditioned by the power distribution measurement and control platform into appropriate signals for controlling each contactor. Simultaneously, the contactor status parameters and voltage / current signals are conditioned by the power distribution measurement and control platform and fed back to the real-time simulator.

[0097] (3) System communication. System communication scheme is as follows: Figure 9As shown, the top-level control generation system sends control instructions and reads system status parameters through UDP communication. The system control unit parses the instructions and 1) sends the load output power control signal to each load and queries the load status information through the CAN communication network; 2) sends the SSPC control signal and status query instruction to 28V distribution boxes 1 and 2 through the CAN communication network; 3) communicates with 270V / 28V DC converters 1 and 2 through two 485 communication channels to control the start and stop of the 270V / 28V DC converter and query the status of the 270V / 28V DC converter.

Figure 10As shown, the power distribution measurement and control module converts the 28V DC power source into ±15V, 5V, and 3.3V, which are used for: 1) the ±15V output power distribution measurement and control module, which powers the current sensors and voltage sensors in 270V distribution boxes 1, 270V distribution boxes 2, and 28V distribution boxes 1, 28V distribution boxes 2; 2) the 5V output power distribution measurement and control module, which powers the SSPC in 28V distribution boxes 1, 28V distribution boxes 2; and 3) the 3.3V power supply for the power distribution measurement and control module core board. Secondly, the power distribution measurement and control module contains multiple system status sampling and control circuits, which collect the voltage, load current, and contactor status of each channel in 2270V distribution boxes 1, 270V distribution boxes 2, 28V distribution boxes 1, and 28V distribution boxes, and control the contactors. The specific functional modules include: 1) Conditioning circuit: Conditions the voltage signals output by the current and voltage sensors to an appropriate range and sends them to the real-time simulation target machine 1; 2) Contactor status sampling: The status of each contactor is sampled through the contactor auxiliary contacts, and the signal is conditioned to an appropriate range and sent to the real-time simulation target machine 1; 3) Isolation amplifier circuit: The isolation amplifier circuit amplifies the discrete contactor controller signal output by the real-time simulation target machine, drives the contactor coil, and realizes control of the contactor. Third, the power distribution measurement and control module uses DSP28335 as the core to complete functions such as communication with the top-level control unit, load communication control, SSPC communication control, networking with 270V / 28V DCDC, and data recording. Specifically, it includes: 1) receiving top-level control instructions through UDP communication, parsing instructions, and sending system status parameters to the top-level control unit; 2) realizing communication networking between the power distribution measurement and control platform and each simulated load through CAN communication, and completing power control of each simulated load in different flight phases according to the top-level control instructions; 3) realizing SSPC communication control in 28V distribution box 1 and 28V distribution box 2 through CAN communication; 4) realizing communication networking with two 270V / 28V DC converters through two-way 485 communication to realize reading of 270V / 28V DC converter status parameters; 5) realizing system status parameter recording through EEPROM.

[0103] The composition of real-time simulator 1 and real-time simulator 2 is shown as follows Figure 11 As shown in the figure, real-time simulator 1 is used to deploy system control algorithms and record system status parameters. Real-time simulator 2 is used to deploy the system's real-time simulation model. Taking real-time simulator 2 as an example, the real-time simulation model development process based on RT-LAB is as follows: Based on the fully digital models of the power generation and distribution systems, they are converted to real-time to complete the model development. The real-time model can display the voltage and current status of the power generation and distribution systems, power conversion devices, and power load simulation units in real time. It can receive control signals from the signal conditioning box via a fiber optic interface and can also send voltage and current signals to the signal conditioning box.
