[0062] Step 105: Conduct simulation calculations in the simulation system and output the simulation results of the generator excitation system.

[0063] Specifically, based on the ADPSS full digital power system simulation device, the present invention proposes a method for simulating and calculating the excitation system of a conventional generator set; the electromagnetic simulation program is more flexible in application, has a shorter simulation step length, and higher simulation result accuracy compared with traditional electromechanical simulation programs.

[0064] For the simulation verification of the generator excitation system using the ADPSS full digital power system simulation device, the present invention proposes a simulation verification method, which consists of several parts including a generator, an excitation system model, and a UDM control module; the present invention realizes the simulation calculation of the generator terminal voltage set value control in the ADPSS full digital power system simulation device, and the parameters can be selected as the actual on-site parameters to be closer to the actual situation; it can verify the parameters of the excitation system model, and also provide a simulation environment for the simulation analysis of the research and development of related equipment, fault analysis, etc.

[0065] The present invention provides a simulation calculation method for realizing the generator terminal voltage set value control in the ADPSS full digital power system simulation device in the electromagnetic simulation program.

[0066] The simulation calculation method provided by the present invention is based on the electromagnetic simulation program ADPSS; the generator parameters and the excitation system model parameters can be directly selected from the electromechanical program, or directly selected as the on-site measured and identified parameters, and at the same time, a UDM control module is built; the method includes:

[0067] (1) In ADPSS on the unit side, use the synchronous generator and the excitation system model described by the Park equation according to the on-site data. The system side is an infinite system or an actual power grid, and a circuit breaker is used to connect the unit to the power grid to form a generator operating condition. See the example in Figure 2 .

[0068] (2) Create a user-defined model UDM control module and use a step module to output the control Figure 1 voltage reference value of the excitation system model in Figure 3In the control logic encapsulation module, the analysis of the input system data and the electrical data output by the generator can be added. Different types of input excitations can be analyzed for output control, so as to realize the verification of the excitation system model parameters, the frequency spectrum analysis of the generator set, and also the simulation analysis of the research and development of related equipment and fault analysis, etc.

[0082] Step 4: Conduct the simulation of the set value control under the no-load condition of the generator, and compare the simulation results with the actual test results. The simulation results of the set value control are shown in Figure 11 。

[0083] Compare the simulation results with the waveform indexes measured on-site of the unit, as shown in Table 3:
