Example text

7 shows a summary of these signal processing aspects in the context of smart girds, emphasizing applications, techniques and specifications. 8 a comprehensive approach to the use of signal processing is illustrated. Here it can be seen that voltage and current signals at a specific point (even in a remote location) can be used to determine impedance, power factors, power flow, stability and so on, where such information can be used by the system operator for more efficient control of the electric grid.

This is true for both high-voltage (HV) and low-voltage (LV) devices. Electric charges build up in thunderclouds to such an extent that they can break through the atmospheric insulation. This may result in an electric discharge from cloud to ground, and such a current can reach 20–200 kA. If a lightning discharge occurs directly or in the vicinity of a transmission line, it will cause the movement of electrical charges (outbreaks). These discharges travel close to the speed of 14 Power Systems Signal Processing for Smart Grids light and move through the power conductors reaching substations.

We also expand on how to apply in an integrated fashion both traditional and advanced signal processing techniques for monitoring and control of power systems, particularly in the context of future complex smart grids. The methods and techniques explore the full range of signals that account for the interaction of a greater number of generation sources and active consumers with non-linear time-varying loads. The increased complexity of the electric grid, prompted by the development and implementation of smart grid technology and systems, requires a higher level of signal processing techniques.
