Abstract
FACTS-control has always to cope with speed and in the case of power flow control with exchange of system wide information. The high speed exchange of data to react on contingencies needs to be ensured to fulfill the requirements of the NISC-architecture according to the specifications in chapter 9. Online monitoring of the system status is needed for the optimization of the FACTS-device applications. Especially for power flow control and power system oscillations a dynamic performance evaluation supports an optimized transmission capability and an adaptive damping control.
Although pioneered already in the 80s, it is not until now phasor measurement units (PMU) have become widely available in power systems [1]. However, since recently wide-area measurement systems based on PMUs are becoming proven technology and are seen by many utilities as one of the most promising ways to gain more detailed information to operate the networks closer to the limits. Typically a wide-area measurement system based on phasor measurements provides access to system-wide data with a time resolution of tens of Hertz. The amount of gathered data becomes large, and the data need proper processing to be used either for the operator support or as part of the control system especially for FACTS. This chapter discusses wide area measurement and control systems as part of the coordinating FACTS-control.
