| In recent years, with the continuous development of our power grid, the demands of the power system's security is also higher and higher. The optical current transformer can measure and monitor the state of power system, to ensure the safety and reliable operation of the system. But due to the restriction of the temperature drift and long-term stable operation of the sensor unit, optical current transformer still can't be used widely. The existing theoretical and experimental are almost to study the whole transformer, So we still need to do further discuss and analysis the specific module of optical current transformer's sensor unit and study the influence of the specific factors, it is facilitate to looking for ways to improve its performance, it is also the aim of we realize the sensor unit simulation platform which used of hybrid simulation.In this paper, we use the Jones matrix as the mathematical model, to realize the analysis program which has think about the device quality, the environmental temperature and the interference by the software of MATLAB. Using the distribution parameters mathematical model, with the element analysis software Ansoft and Ansys we have established the powerful database of magnetic field and temperature field in different conditions, then, we call the corresponding magnetic field and temperature field in the program, realize the simulation environment and the actual magnetic and temperature field of sensor unit are agreement. Finally, we editor platform interface by the LabVIEW software to make the platform's operation more convenient.Through the compare of simulation output and theoretical analysis results, we has proved the effectiveness and correctness of our simulation. Using this simulation platform as a analysis, preliminary analysis the influence of magnetic field uniformity, temperature field and different disturbance field. Demonstrating the function and application value of this paper's simulation platform. |
