[0043] The method and system for real-time simulation interconnection between different simulation platforms based on delay decoupling provided by the present invention include: calculating the interface delay between at least two different real-time simulation platforms; determining the decoupling interface position according to the interface delay; calculating the values ​​of the decoupling inductor and the decoupling resistor according to the unit length inductance value, the unit length capacitance value and the interface delay of the line at the interface position; configuring the decoupling interface parameters according to the calculated values ​​of the decoupling inductor and the decoupling resistor to realize the voltage and current signal interconnection between different real-time simulation platforms. The present invention realizes the transmission of electrical signals between two platform models, and solves the problem of simulation result deviation caused by data intercommunication delay between different simulation platform models.

[0044] In one embodiment of the present invention, Figure 1 , Figure 2 As shown, a real-time simulation interconnection method between different simulation platforms based on delay decoupling is provided. This embodiment takes the method applied to a terminal as an example. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. The real-time simulation interconnection method provided in this embodiment can not only be used between different simulation platforms, but can also be applied to other fields to communicate data between other platforms. This embodiment takes the real-time simulation interconnection between HYPERSIM and RTLAB as an example, and does not limit the interconnection part between the platforms. In this embodiment, the method includes the following steps:

[0045] 1) Calculate the interface delay between at least two different real-time simulation platforms;

[0046] 2) Determine the decoupling interface position based on the interface delay;

[0047] 3) Calculate the values ​​of the decoupling inductor and the decoupling resistor according to the inductance per unit length, the capacitance per unit length and the interface delay of the line at the interface position;

[0048] 4) Configure the decoupling interface parameters according to the calculated values ​​of the decoupling inductance and decoupling resistance to achieve the interconnection of voltage and current signals between different real-time simulation platforms.

[0049] In the above step 1), before configuring the decoupling interface of the interconnection platform, it is necessary to first measure the interface delay of the two real-time simulation platforms. Figure 3As shown, calculating the interface delay of at least two different real-time simulation platforms includes the following steps:

[0050] 1.1) In T 1 Sending a pulse signal from the first real-time simulation platform 1 to the second real-time simulation platform 2 at all times;

[0051] 1.2) When the second real-time simulation platform 2 is in T 2 After receiving the pulse signal at time, in the same simulation cycle (T 2 moment) returns the pulse signal to the first real-time simulation platform 1;

[0052] 1.3) In T 3 At this moment, the first real-time simulation platform 1 receives this pulse signal;

[0053] 1.4) Calculate the delay between the first real-time simulation platform 1 and the second real-time simulation platform 2.

[0054] The delay calculation formula is:

[0055]

[0056] Among them, T 1 is the moment when the first real-time simulation platform sends a pulse signal, T 2 is the moment when the second real-time simulation platform receives and sends the pulse signal, T 3 The time when the first real-time simulation platform receives the pulse signal back; ΔT 12 is the signal delay from the first real-time simulation platform to the second real-time simulation platform, ΔT 21 ΔT is the signal delay from the second real-time simulation platform to the first real-time simulation platform. s is the simulation step size.

[0057] In this embodiment, the simulation steps of the two simulation platforms HYPERSIM and RTLAB are equal, so the delay of signal transmission between the HYPERSIM and RTLAB simulation platforms can be expressed as 2ΔT s In this form, it takes a 2-step delay for HYPERSIM to send a signal to RTLAB, and it takes a 2-step delay for RTLAB to receive the signal and return it to HYPERSIM.

[0058] In the above step 2), the configuration of the decoupling interface is based on the signal transmission delay, so it is necessary to select the part with larger transmission delay in the system as the decoupling part. In this embodiment, determining the position of the decoupling interface according to the interface delay includes: selecting the position of the long transmission line in the real-time simulation model as the decoupling part.

[0059] The selection principles are:

[0060] The location where the transmission line length is more than 5 km is selected as the decoupling access point, and the simulation results are more accurate;

[0061] Select locations with simple circuit structures as interfaces to minimize the number of interfaces that need to be decoupled.

[0062] Keep the simulation model size on both sides of the interface consistent to avoid large differences in simulation time length on both sides.

[0063] In the above step 3), the values ​​of the decoupling inductor and the decoupling resistor are calculated using the following formula:

[0064]

[0065] Among them, L 0 is the unit inductance of the line at the decoupling interface, C 0 is the unit capacitance value of the line at the decoupling interface; Δk is the required line length of the decoupling interface; R is the resistance value at the decoupling interface; u 1 u is the voltage control signal of the controlled voltage source of the first real-time simulation platform at the decoupling interface; 2 is a voltage control signal of a controlled voltage source of the second real-time simulation platform at the decoupling interface; i 1 is the current signal of the first real-time simulation platform at the delay decoupling interface; i 2 is the current signal of the second real-time simulation platform at the delay decoupling interface; ΔT 12 is the signal delay from the first real-time simulation platform to the second real-time simulation platform, ΔT 21 ΔT is the signal delay from the second real-time simulation platform to the first real-time simulation platform; s is the simulation step size.

[0066] In the above step 4), after configuring the delay decoupling interface of simulation platform 1 and simulation platform 2 according to the above formula, the voltage and current signal interconnection between the real-time simulation platforms can be satisfied, and the steady-state power level before and after passing through the interface can be kept consistent with the power level of the actual system, and the voltage and current level of the transient characteristics can be kept consistent. This method can also be extended to the interconnection between other devices and simulation platforms, such as Figure 4 The interconnection between the new energy station simulation model and the converter station simulation model is shown.

[0069] An interface position module determines the decoupling interface position according to the interface delay;

[0070] A parameter calculation module calculates the values ​​of the decoupling inductor and the decoupling resistor according to the inductance per unit length, the capacitance per unit length and the interface delay of the line at the interface position;

[0071] The configuration module configures the decoupling interface parameters according to the calculated values ​​of the decoupling inductance and the decoupling resistance to realize the interconnection of voltage and current signals between different real-time simulation platforms.

[0072] In the above embodiment, the delay calculation module includes:

[0073] Pulse sending module, used in T 1 Sending a pulse signal from the first real-time simulation platform to the second real-time simulation platform at all times;

[0074] Pulse transceiver module, when the second real-time simulation platform is in T 2 After receiving the pulse signal at the moment, the pulse signal is returned to the first real-time simulation platform within the same simulation cycle;

[0075] Pulse receiving module, at T 3 At this moment, the first real-time simulation platform receives this pulse signal;

[0076] The calculation module calculates the delay between the first real-time simulation platform and the second real-time simulation platform.
