[0048] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the following described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0049] Embodiment one
[0050] Please refer to Figure 1 , Figure 1 A step flow chart of a long-distance computing power joint real-time simulation method provided for the first embodiment of the present application.
[0051] The long-distance computing power joint real-time simulation method provided by the present application comprises the following steps:
[0052] Before step 101 is executed, the following steps S11-S13 are also included:
[0053] S11, obtain the communication delay value between two remote computing powers;
[0054] S12, calculate the ratio between the communication delay value and the preset simulation step value;
[0055] S13, determine the delay multiple based on the positive integer of the ratio.
[0056] It should be noted that first, the communication delay Tdelay between two remote simulation computing powers is measured, and then Tdelay / Ts is rounded up to obtain the integer multiple of the delay, i.e., the delay multiple, through N=ceil(Tdelay / Ts).
[0057] Step 101, obtain the target voltage signal, and perform communication delay processing on the target voltage signal according to the preset delay multiple.
[0058] Optionally, step 101 includes the following steps S21-S23:
[0059] S21, obtain the initial voltage signal;
[0060] S22, perform signal processing on the initial voltage signal to generate the target voltage signal;
[0061] S23, perform communication delay processing on the target voltage signal according to the preset delay multiple.
[0062] It should be noted that the initial voltage signal is a voltage source (Three) signal, which is a three-phase voltage source or a single-phase voltage source signal source.
[0063] In specific implementation, referring to Figure 2 shown, from left to right, obtain the initial voltage signal of the three-phase voltage source or the single-phase voltage source signal source, and the initial voltage signal enters the "phase domain to mode domain" (Three to Two) conversion module. The module converts the initial voltage signal of the three-phase signal into a mode (two-phase or direct current) signal, i.e., obtains the target voltage signal.
[0064] The target voltage signal passes through a discrete variable time delay unit (Discrete Variable Time Delay), which means that the signal will be delayed for a certain time in this link, and the time is variable. The delay time is Tau-Ts N, where Tau is the time required for an electrical signal to be transmitted from one end of a line to the other end), and Ts is the simulation step.
[0065] It should be noted that the delay factor N is determined in step S13, and then the delay time Ts N, which represents the artificial delay introduced in the simulation, is used to compensate for the actual communication delay Tdelay.
[0066] Specifically, assume the simulation step Ts=50 microseconds, and the actual communication delay Tdelay=5 milliseconds.
[0067] The traditional method requires: TdelayTs, but obviously 5 milliseconds> 50 microseconds, which does not meet the condition and cannot perform long-distance simulation.
[0068] When the present application is implemented, N = ceil(Tdelay / Ts) = ceil(5ms / 50μs) = 100, which means that 100 simulation steps of delay are introduced in the simulation to match the actual communication delay.
[0069] The reason for achieving long-distance computing power joint real-time simulation by introducing N simulation steps of delay is as follows:
[0070] a) Time alignment: ensures that data exchange between different nodes is time consistent, even if they are physically far apart.
[0071] b) Buffer mechanism: reserves enough time for data transmission, avoiding data loss or synchronization problems.
[0072] c) Error control: by precisely matching the actual delay, the error introduced by communication delay is minimized.
[0073] For the determination of the optimal N value, theoretically N should be equal to ceil(Tdelay / Ts), but in practical applications, factors such as communication delay fluctuations, system response time, etc. need to be considered, therefore, a series of experiments need to be conducted to determine the optimal N value.
[0074] Experimental setup:
[0075] Simulation step Ts=50 microseconds
[0076] Communication delay Tdelay=5 milliseconds
[0077] Theoretical N value = ceil(5ms / 50μs) = 100
[0078] Different N factors (i.e. the ratio of the actual N value used to the theoretical N value) are tried, and the response error of the system is observed.
[0079] The experimental results are shown in Table 1 below:
[0080] Table 1. Experimental results
[0081]
[0082] As shown in Table 1 above, 1. When N factor is 0.5 (i.e. N = 50), the delay compensation is insufficient, resulting in a large error; 2. When N factor is 1.0 (i.e. N = 100, theoretical value), the error is significantly reduced; 3. As the N factor continues to increase, the error further decreases; 4. When the N factor is 2.5 (i.e. N = 250), the error reaches a minimum.
[0083] Therefore, the optimal N value is selected as follows: although the error is smallest when the N factor is 2.5, considering the calculation resources and real-time requirements, it is recommended to select the N factor between 1.5 and 2.0, i.e. N value between 150 and 200. This provides good error control while maintaining reasonable calculation complexity.
[0084] In the above example, the optimal choice is N = 150, i.e. optimal delay time = Ts N = 50μs 150 =7.5ms.
[0085] This value is slightly larger than the actual communication delay (5ms), providing additional stability margin for the system while maintaining low simulation error.
[0086] By introducing the carefully designed delay Ts N, successful long-distance computing power joint real-time simulation is achieved. Experimental data shows that selecting N slightly larger than the theoretical value (1.5 times in this embodiment) can maintain low error while providing sufficient system stability. This method not only overcomes the distance limitation of traditional methods, but also ensures the accuracy and reliability of the simulation.
[0087] It provides a powerful tool for real-time simulation of large-scale, cross-regional power systems, helping to improve the analysis capability and operation efficiency of the power grid. In the future, the adaptive selection algorithm of N value can be further optimized to adapt to different network conditions and simulation requirements.
[0088] Step 102, calculate the difference between the target voltage signal after delay processing and the preset communication delay value, send the difference to the opposite system, and receive the feedback of the opposite signal from the opposite system.
[0089] Optionally, step 102 includes steps S31-S34:
[0090] S31, input the target voltage signal after delay processing into the first multiplier, and calculate the first multiplication value between the target voltage signal after delay processing and the first preset fixed value;
[0091] S32, calculate the difference between the first multiplication value and the preset communication delay value;
[0092] S33. Input the difference into the second multiplier and calculate the second multiplication value between the difference and the second preset fixed value;
[0093] S34. Send the multiplication value to the peer system and receive the peer signal fed back by the peer system.
[0094] It should be noted that after the target voltage signal is delayed, it enters the first multiplier and is multiplied by a first preset fixed value K, where K = (1 + h) / Z, to obtain the first multiplier value. K can also be expressed as:
[0095]
[0096] In the formula, f represents the signal frequency; Indicates the signal phase; The reference amplitude is represented by t; the current time is represented by t; and the estimated amplitude of the current voltage or current is represented by A. ; ; Where r, l, and c all represent unit length parameters, and d represents line length.
[0097] In specific implementation, refer to Figure 2 As shown, after subtracting the first multiplier value from the preset communication delay value, the difference is input into the second multiplier, which is to multiply the difference by the second preset fixed value (1+h) / 2 and send it to the peer system, i.e. the peer control module of the line, and receive the peer signal fed back by the peer system, i.e. the signal fed back by the peer.
[0098] Step 103: Delay the difference and determine the target current signal based on the delayed difference and the signal at the other end.
[0099] Optionally, step 103 includes the following steps S41-S44:
[0100] S41. Perform delay processing on the difference according to the preset delay value;
[0101] S42. Input the difference after delay processing into the third multiplier, and calculate the third multiplication value between the difference after delay processing and the third preset fixed value;
[0102] S43. Calculate the sum between the third multiplier and the signal at the other end;
[0103] S44. Perform signal processing on the sum to generate the target current signal.
[0104] It should be noted that, referring to Figure 2As shown, while the difference value is input into the second multiplier, the difference value also needs to be subjected to delay processing of N simulation steps, that is, the difference value is subjected to delay processing according to a preset delay value. .
[0105] After the difference value is subjected to delay processing, the difference value enters a third multiplier and is multiplied by a third preset fixed value (1+h) / 2 to obtain a third multiplication value.
[0106] The third multiplication value and the peer signal fed back by the peer system are summed, the sum value obtained by the summation is subjected to coordinate transformation from a modulus domain to a phase domain, and is output to an external controlled current source, representing the end of updating the historical current of the entire sub-module, that is, the target current signal can be obtained.
[0107] Optionally, the method further includes the following steps S51-S53:
[0108] S51, inputting the sum value into a fourth multiplier to calculate a fourth multiplication value between the sum value and a fourth preset fixed value;
[0109] S52, performing communication delay processing on the fourth multiplication value according to a preset delay multiple;
[0110] S53, setting the fourth multiplication value subjected to the communication delay processing as a new preset communication delay value, and jumping to execute the step of obtaining the target voltage signal and performing communication delay processing on the target voltage signal according to the preset delay multiple until a new target current signal is generated.
[0111] It should be noted that the sum value obtained by the summation in step S43 is input into a fourth multiplier and multiplied by a fourth preset fixed value h to obtain a fourth multiplication value, and the fourth multiplication value is subjected to delay processing by a discrete variable time delay unit (Discrete Variable Time Delay), which means that the signal will be delayed for a certain time in this link, and the time is variable. The delay time is Tau-Ts N, wherein Tau is the time required for an electrical signal to be transmitted from one end of a line to the other end, and Ts is a simulation step. The value subjected to the delay processing is the preset communication delay value.
[0112] In specific implementation, when the new preset communication delay value is obtained, step 101 is executed until the target current signal at the current time is obtained.
