ABSTRACT: This paper firstly reviews the recent
development in power system protection and control, with special attention paid
to the wide-area and integrated protection, in order to look into future development
of integration of protection and control for smart grids. This paper mainly reports
on the development of integrated wide area protection and control for power
systems. The concept of integrated wide area protection and control is
introduced, in which a hierarchical protection and control system provides the
protection and control of wide area or regional power substations/ plants and
their associated power network. The system is mainly divided into three levels,
the local, the substation/plant and the wide area/regional protection and
control. The integrated functions at each level are described in details with
an aim to develop an optimal coordination mechanism between the levels. One of
the core elements in the system is the synchronised wide area communication
network between the substations and the protection and control system, in which
latest communication technology is employed. Another important player in the
system is the wide area synchronized protection and control information
platform, which not only enables the fusion three line of defence for power
system protection and control, but also provides a perfect tool for the
application of cloud computing to substations and power networks.
