Description

Technical Field

[0001] This invention belongs to the field of electromechanical dynamic characteristic simulation technology of power grids with wind power access, and specifically relates to an electromechanical dynamic simulation method for a dynamic model experimental platform of a power grid with wind power access. Background Technology

[0002] For research on the frequency dynamic characteristics of actual power grids with a high proportion of wind power, rapid technological development relies heavily on extensive testing and verification. Since conducting experiments in actual power grids is extremely difficult and time-consuming, the establishment of dynamic model experimental platforms has made it possible to conduct related experiments in the laboratory. Researchers can first conduct relevant experiments on the platform, and then apply the technology to the actual power grid after it is perfected and feasible. The emergence of dynamic model experimental platforms has greatly promoted the research and development of wind power technology and made valuable contributions to the development of wind power grid connection in my country.

[0003] The simulation methods used by the wind turbine simulator and synchronous machine simulator in the dynamic model experimental platform to simulate actual wind turbine units and actual power grids mainly employ scaling and inertia compensation strategies to address the issue that the simulator's rotational inertia is much smaller than that of the actual simulated turbine unit. However, this simulation method is only suitable for individual simulations by the wind turbine simulator or synchronous machine simulator. If only scaling and inertia compensation algorithms are used to simulate an actual power grid with wind power integration in the dynamic model experimental platform, the wind turbine and synchronous machine in the system need to be set to the same simulation scaling factor. Therefore, the proportion of wind power in the simulated power grid is the same as the capacity proportion of the wind turbine simulator in the experimental platform, making it difficult for the system to simulate actual power grids with different wind power proportions.

[0004] Based on the above situation, there is an urgent need for an electromechanical dynamic simulation method for a dynamic model experimental platform with wind power access to the grid based on a capacity compensation algorithm. This method can simulate the electromechanical dynamics of wind turbines and synchronous machines under different scaling factors by adding torque compensation, so that a hardware platform with a fixed capacity ratio can simulate the electromechanical dynamics of the grid with different wind power proportions.

[0093] Table 1 Main parameters of the dynamic model experimental platform

[0094]

[0095] To enable the dynamic model experimental platform to simulate the actual power grid, the wind power and synchronous power sources in the actual power grid are first equated to a single wind turbine and a single synchronous machine. Therefore, this invention equates the actual power grid to a simple power grid frequency dynamic response model, such as... Figure 3 As shown in Table 2, the main parameters of the power grid frequency dynamic response model are shown in Table 2.

[0096] Table 2 Main parameters of the power grid frequency dynamic response model

[0097]

[0098] The electromechanical dynamic simulation method of the grid-connected wind power dynamic model experimental platform based on the capacity compensation algorithm of the present invention is specifically implemented in the following steps:

[0099] Step 1: Equip the actual power grid with a power grid frequency dynamic response model. The equivalent model consists of one equivalent synchronous machine, one equivalent wind turbine, and an equivalent load. Determine the rated capacity S of the wind turbine and synchronous machine in the equivalent model. wtN S synN The values ​​are 0.6 MVA and 1.4 MVA, respectively. Simultaneously, the moment of inertia J of the synchronous machine is determined. syn =315.27 kgm 2 Rated frequency f synN =60Hz, number of pole pairs p=2 and equivalent load power P d =0.861MW, where the equivalent rotational inertia J of the synchronous machine syn The calculation formula is:

[0100]

[0101] In the formula, H syn The inertial time constant of the equivalent synchronous machine is 4s.

[0102] Step 2: Determine the rated capacity S of the fan simulator and the synchronous machine simulator within the dynamic model experimental platform. wtN_test S synN_test Determine the moment of inertia J of the synchronous machine simulator, given that the values ​​are 15kVA and 25kVA respectively. syn__test = 4.196 kgm 2 .

[0104] Step 4: Calculate the scaling factors between the capacity of the wind turbine simulator, the capacity of the synchronous machine simulator, and the power of the regenerative load in the dynamic model experimental platform and the capacity of the wind turbine, the capacity of the synchronous machine, and the power of the load in the actual power grid, and denote them as n. w n s n d The calculation formula is:

[0105]

[0106] Step 5, calculate the additional compensation torque T comp for:

[0111] In the formula, T m_test It is a mechanical torque command that the synchronous machine simulator adjusts through the frequency of the governor-prime motor system.

[0112] The following experiment verifies this, setting the system to experience a sudden increase in load power at 10 seconds. The experimental results are as follows: Figure 4 As shown in the figure, the frequency response curve of the simulated actual power grid is given by simulation, while the frequency response curves of both the traditional electromechanical dynamic simulation method and the capacity-compensated electromechanical dynamic simulation method of this invention are obtained experimentally. As can be seen from the figure, the minimum deviation between the simulated frequency and the actual frequency under the traditional method is 6.88%, while the minimum deviation under the method of this invention is 0.99%. This indicates that under the traditional method, the simulated frequency deviates when the wind power ratio of the simulated power grid is inconsistent with the hardware platform, making it impossible to accurately obtain the frequency dynamic characteristics of the simulated actual power grid. This problem is solved by applying this invention.

[0113] In summary, this invention designs an additional torque compensation strategy that enables electromechanical dynamic simulation of wind turbines and synchronous machines at different scaling factors on the dynamic model experimental platform, allowing a hardware platform with a fixed capacity ratio to simulate the electromechanical dynamics of power grids with different wind power ratios.
