Abstract
With the rapid development of economy in our country, current the construction of
intelligent power grid, the substation equipment and device also began to high science
and technology development. Currently the substation has basically realized the
modernization and automation, the equipment is set technology. In this case, you need to
adapt to the high level of operation management, so as to effectively guarantee the
normal operation of the equipment, avoid the happening of the fault. But in the current
our country the majority of the substation, its operation and management is still in the
extensive mode of management, not compatible with the level of automation and
modernization, which result in the low productivity of substation operation, frequent
accidents, unable to meet the needs of the modern equipment management, so
strengthening the operation of the substation management is very necessary, will
effectively promote the stability and reliability of the power grid operation. This paper
studies the substation compositions, introduces the development of substation. Finally, the
advantage of smart substation, the key technology and management are analyzed in
detailed.
Keywords: intelligent, substation, operation, management
1. Introduction
With the rapid development of economy in our country, the constant innovation of
science and technology, lead to the electric power industry is also in constant progress.
Because of the electric power industry development in our country starts late, though
developing rapidly, but there are still many problems, in the way of rapid development,
facing many aspects of the intervention and restrictions, makes the substation in our
country still exists many defects and shortcomings. Such as: currently, there is a
widespread power supply substation long radius, poor quality of voltage, low power
factor, reactive power allocation is not reasonable, etc. So we should according to the
operation of problems to work out some strategies to improve maintenance, avoid the
occurrence of related operation failure and safety problems.
To explore for smart grid in China has been in progress. At present, the domestic
power grid can't meet the demand of the development of photovoltaic industry, so
our country will build with "extreme pressure as the core" of the "strong smart grid",
in order to solve the problem of grid-connected photovoltaic (pv), promote the use
of new energy. Smart grid in China is high voltage network backbone network frame,
all levels of power grid, the coordinated development of strong power grid as the
foundation, use advanced communications, information and control technology[1].
From around the world to the smart grid and new energy sources such as solar
energy power generation will invest a lot of money; this is due to the development
of new energy power generation based on the smart grid development. Mart grid, its
