   USER-DEFINED BLOCK-ORIENTED MODELING OF FACTS DEVICES FOR LARGE POWER SYSTEM STABILITY STUDIES
By B. Gick; I. Erlich; Th. Weber [View]
[Download]

Abstract: Power System planning includes more and more the usage of new components like FACTS devices. So the modeling of FACTS devices has to be regarded in Power Application Software, e.g. load flow and transient stability modules. The PSD (Power System Dynamics) stability program enables the user to define models or extend existing models by a universal block-describing language for modeling controls and FACTS devices as well.

   Measurements and simulation of DC drive harmonics on an interconnected offshore system with long sub-sea cables

Abstract: This paper describes the effects of linking two offshore installations, with two 22 !cm sub-sea cables. It is shown using site measured data, that the non-linear, six-pulse drilling drives can excite the power system's natural frequency. Due to the differing type of generation available, the system natural frequency changes dramatically as different combinations of generation are brought on-line. It is also shown that when there are two cables feeding different systems, there is the potential for an inter-cable resonance. Site rneastuernents are compared with results from both time and frequency domain analysis of the system obtained using the SABER simulator. Good eorrelation between site measured and simulated data is demonstrated. The paper eoncludes by explaining how the results of this theoretical analysis have been used by the offshore operator to derive system operating policy.
