Power System Theoretical Line Loss Cloud Computing System and Method
Thereof
The invention relates to the field of power system theoretical line loss calculation
and analysis, in particular to a power system theoretical line loss cloud computing
system and method.
Line loss is the power loss generated in the process of power transmission. Line
loss rate is an index to measure the level of power grid operation and management,
and it is also an important reference for smart grid planning and construction.
Theoretical line loss calculation can comprehensively reflect the power grid planning
and design level, power grid construction level, technical progress level, production
operation and management level, and is also an important technical management
means for power supply enterprises. With the expansion of power grid scale, the
importance of theoretical line loss calculation has become increasingly prominent.
How to accurately calculate the current loss of power grid network and how to take
effective measures to reduce line loss have become the focus of energy conservation
and emission reduction. However, compared with other work, line loss management
has some particularity. The data collection and information maintenance in the
maintenance period are required to be uninterrupted, and the workload is evenly
distributed in the whole-time axis. At the same time, there is a calculation period with
a large workload of loss calculation and result analysis, that is, there is a significant large-scale sudden calculation amount, especially for large-scale power grids. The existing theoretical line loss calculation system mainly has the following shortcomings:
(1) The existing theoretical line loss calculation system often adopts the mode of
independent design, independent construction and self-maintenance, which has
problems such as long construction period, high construction cost, inadequate
maintenance and inflexible expansion.
(2) It is difficult to summarize the calculation results of several departments in
charge, and it is impossible to make timely and comprehensive analysis. In addition,
there are still cases where the calculation standards are not uniform and standardized;
(3) In addition, load measurement and theoretical calculation of line loss have
high requirements for data simultaneity and accuracy, and the off-line calculation
methods currently adopted affect the measurement accuracy and calculation accuracy
to a certain extent;

of hardware resources and waste of investment, and the construction cost is relatively
high.
