DECOMPOSITION AND MITIGATION OF A DISTURBANCE BEING PRESENT AT AN ELECTRIC CONNECTION BETWEEN AN ELECTRIC POWER GENERATING SYSTEM AND A POWER GRID |
摘要 |
<p>A disturbance on an electric signal at an electric connection between an electric power generating system and a power grid is decomposed into a first disturbance with a first strength assigned to the electric power generating system and a second disturbance with a second strength assigned to the power grid. A voltage value of a voltage of the electric signal is measured. A current value of a current of the electric signal is measured. A value of an open circuit voltage of an equivalent voltage source is calculated based on the measured voltage value, the measured current value and a characteristic equivalent impedance of the electric power generating system so that the electric power generating system is in a harmonic model. The strength of the first disturbance is determined based on the calculated value of the open circuit voltage of the equivalent voltage source.</p> |
