| Abstrakt v dalším jazyce: | The paper presents the methodology and results of the generator and electromachine excitation system model parameters computations. The computations were based on real dynamic waveforms obtained from possible to perform in Rybnik Power Plant measurements of the generator steady state disturbed with different test disturbances. The disturbances used for parameters estimation are a load rejection test and a step change in AVR voltage reference value by +/- 5%. The voltage controller was operating (automatic control) during the test. The methodology of parameter determination consists in performing a number of simulations and comparing the simulation results with test results. The estimation process is iterative and in each iteration the model parameters are changed so that the simulated response becomes as close as possible to the test results. In the effect, the parameter estimation problem is transformed into an optimisation one, where the objective function is defined as the squared deviations between the test and simulation results and then it is locally minimised using the large-scale, trust-region, reflective Newton gradient algorithm. The methodology of filtering measurement signals recorded is also given in the paper. |
