高压及超高压输电线路的线路参数测量是一项程序比较复杂且对技术要求较强的工作，且存在一定的安全风险。所以为作好线路参数测量工作，必须需对参加线路参数测量的高压试验人员进行技术培训。由于高压及超高压输电线路有严格的停电时间限制，所以到现场培训比较困难，比较好的选择是在试验室进行模拟培训。但是现有技术中，并没有相应的模拟输电线路供高压试验人员进行技术培训时使用。Line parameter measurement of high-voltage and ultra-high-voltage transmission lines is a job with complex procedures and strong technical requirements, and there are certain safety risks. Therefore, in order to do a good job in line parameter measurement, it is necessary to carry out technical training for high-voltage test personnel participating in line parameter measurement. Since high-voltage and ultra-high-voltage transmission lines have strict power outage time limits, it is difficult to conduct on-site training. A better option is to conduct simulation training in the laboratory. However, in the prior art, there is no corresponding simulated transmission line for high-voltage test personnel to use during technical training.

所述参数设置模块11用于接收用户设置的所述模拟输电线路的目标参数，并根据所述模拟输电线路的目标参数转换并生成对应的模拟参数。进一步的，所述目标参数为所述模拟参数的N倍，N为正整数。例如，N为10000，而用户设置的所述模拟输电线路的目标输电电压（目标参数）为10k伏，则参数设置模块11将目标参数转换并生成的对应模拟输电电压（模拟参数）为1伏。The parameter setting module 11 is configured to receive target parameters of the simulated transmission line set by the user, and convert and generate corresponding simulation parameters according to the target parameters of the simulated transmission line. Further, the target parameter is N times the simulation parameter, and N is a positive integer. For example, N is 10000, and the target transmission voltage (target parameter) of the analog transmission line set by the user is 10 kV, then the parameter setting module 11 converts the target parameter and generates a corresponding analog transmission voltage (analog parameter) of 1 volt .
所述功率输出模块12用于根据所述参数设置模块所生成的模拟参数，在所述输电线路上输送对应的功率；所述模拟参数反应所述输电线路上实际输送的功率情况。若模拟输电电压（模拟参数）为1伏，则后续功率输出模块12施加在输电线路13上的电压就是1伏。The power output module 12 is used to transmit corresponding power on the transmission line according to the simulation parameters generated by the parameter setting module; the simulation parameters reflect the actual power transmission conditions on the transmission line.

Here, the multiple N used by the parameter processing module 23 to convert the analog parameter to generate the target parameter is consistent with the multiple N of the corresponding analog parameter converted and generated by the simulated transmission line 1 from the target parameter. For example, if the multiple N of the corresponding simulation parameter converted from the target parameter by the simulation transmission line 1 is 10000, then the multiple N used by the parameter processing module 23 to convert the simulation parameter to generate the target parameter is also 10000. If the simulated transmission voltage (analog parameter) of the transmission line 13 obtained by the parameter measurement module 22 is 1 volt, the parameter processing module 23 converts the simulated parameter and generates a corresponding target transmission voltage (target parameter) of 10 kV.

In this embodiment, the steps of the method for simulating a transmission line will be described in more detail. The method for simulating a transmission line is shown in Figure 4, including:
步骤S201，模拟输电线路根据用户设置的模拟输电线路目标参数；所述模拟输电线路目标参数仅为通过所述仿真线路参数测量仪2能够测出的参数，并不反应所述输电线路上实际输送的功率情况。本实施例中，所述模拟输电线路目标参数包括：正序阻抗、零序阻抗、正序电容、零序电容、输电电路长度、功率等参数。Step S201, simulating the transmission line according to the simulated transmission line target parameter set by the user; the simulated transmission line target parameter is only a parameter that can be measured by the simulated line parameter measuring instrument 2, and does not reflect the actual transmission on the transmission line power situation. In this embodiment, the target parameters of the simulated transmission line include: positive sequence impedance, zero sequence impedance, positive sequence capacitance, zero sequence capacitance, transmission circuit length, power and other parameters.
步骤S202，在仿真线路参数测量仪与所述模拟输电线路之间搭建正确的测量回路。图2提供了一种实际的接线情况。Step S202, building a correct measurement loop between the simulated line parameter measuring instrument and the simulated transmission line. Figure 2 provides an actual wiring situation.
步骤S203，模拟输电线路根据所述目标参数转换并生成对应的模拟参数；所述模拟参数反应所述输电线路上实际输送的功率情况。进一步的，所述目标参数为所述模拟参数的N倍，N为正整数。例如，N为10000，而用户设置的所述模拟输电线路的目标输电电压（目标参数）为10k伏，则参数设置模块11将目标参数转换并生成的对应模拟输电电压（模拟参数）为1伏。In step S203, the simulated power transmission line is transformed according to the target parameters and corresponding simulation parameters are generated; the simulated parameters reflect the power actually transmitted on the power transmission line. Further, the target parameter is N times the simulation parameter, and N is a positive integer. For example, N is 10000, and the target transmission voltage (target parameter) of the analog transmission line set by the user is 10 kV, then the parameter setting module 11 converts the target parameter and generates a corresponding analog transmission voltage (analog parameter) of 1 volt .
步骤S204，模拟输电线路根据所述模拟参数，在所述输电线路上输送对应的功率。所述模拟参数反应所述输电线路上实际输送的功率情况。若模拟输电电压（模拟参数）为1伏，则后续施加在输电线路13上的电压就是1伏。Step S204, simulating the transmission line to transmit corresponding power on the transmission line according to the simulation parameters. The simulated parameters reflect the power situation actually transmitted on the transmission line. If the simulated transmission voltage (analog parameter) is 1 volt, the subsequent voltage applied to the transmission line 13 is 1 volt.

In this step, the multiple N used to convert the simulation parameter to generate the target parameter is consistent with the multiple N of the corresponding simulation parameter converted and generated from the target parameter in step 203 .
例如，若步骤203中将目标参数转换并生成的对应模拟参数的倍数N为10000，则本步骤中将模拟参数转换生成目标参数使用的倍数N也为10000。若步骤S205中测得输电线路的模拟输电电压（模拟参数）为1伏，则本步骤中将模拟参数转换并生成的对应目标输电电压（目标参数）为10k伏。For example, if in step 203 the multiple N used to convert the target parameters and generate corresponding simulation parameters is 10000, then the multiple N used to convert the simulated parameters to generate target parameters in this step is also 10000. If the simulated transmission voltage (analog parameter) of the transmission line measured in step S205 is 1 volt, then the corresponding target transmission voltage (target parameter) generated by converting the simulated parameter in this step is 10 kV.
