This book is written for engineers involved in the operation, control, and
planning of electric power systems. In addition, the book provides information and
tools for researchers working in the fields of power system security and stability. The
book consists of two volumes. The first volume provides traditional techniques for the
stability analysis of large scale power systems. In addition, an overview of the main
DRIVERS and requirements for modernization of the traditional methods for online
applications are discussed. The second volume provides techniques for online security
assessment and corrective action studies. In addition, the impact of variable generation
on the security of power systems is considered in the second volume. The first volume
may be considered as a background builder while the second volume is intended for
the coverage of edge techniques and methods for online dynamic security studies.

With global DRIVERS such as better energy
consumption, energy efficiency and reduction of
greenhouse gases, CO 2 emission reduction has become
key in every layer of the value chain. Power Electronics
has definitely a role to play in these thrilling challenges.
From converters down to compound semiconductors,
innovation is leading to breakthrough technologies. Wide
BandGap, Power Module Packaging, growth of Electric
Vehicle market will game change the overall power
electronic industry and supply chain. In this presentation
we will review power electronics trends, from
technologies to markets.
Since OpenStreetMap (OSM) appeared more than ten years ago, new
collaborative mapping approaches have emerged in different areas and have become
important components of localised information and services based on localisation.
There is now increased awareness of the importance of the space-time attributes of
almost every event and phenomenon. Citizens now have endless possibilities to
quickly geographically locate themselves with an accuracy previously thought
impossible. Based on these societal DRIVERS, we proposed a number of collaborative
mapping experiments (“mapping parties”) to delegates of a large open-source
geospatial conference and to citizens of the conference’s host city during July 2015.

3-phase Sensor-less Fan Motor DriverAM2355NThe AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (BackElectro-Motive Force) of the motor in rotation and provides corresponding commutation current tothe motor. Rotation speed can be controlled by PWM input signal. The DRIVERS include LockDetection, Thermal Shutdown, and Over-current Protection. Forward and Reverse control.www.junmintech.com
