摘要

We can observe in all electrical systems in the world, cc. 0.2,…, 0.35 Hz oscillations in state variables in steady state operation. The amplitude of these — so called inter-area oscillations — is growing going away from the centre of a large electrical power system. In the UCTE (European) system in the centre (near the German-French border) the amplitude of oscillations in frequency deviation time function is less then 2 mHz and near the borders (at present: Greece, Poland, Portugal, Romania, etc.) greater than 6 mHz, in steady state operation. Our ten years' experience has shown that PSSs, realized with “conventional” stages are not efficient in inter-area frequency domain. In addition, these instruments have a disadvantage: there are frequency intervals in the operating range of PSSs in which the PSSs increase the amplitude of active power oscillations and reactive, too; which are exported into the network. In our former activity we presented the model investigation to solve the problem by intervention into the turbine governor [1], [2]. In this paper the realization of the method is shown.
