Abstract
The collaborative system for power grid operation mode calculation implements data management of multi-level paralleling operated dispatching departments indifferent places and joint operation mode calculation, which is based on the calculated data of power grid operation modes. The transient stability analysis monitors the components of electrical variation curve through the network transmission to the web page. When more users and more curves reach a certain extent, the overall simulation time is longer and the curve is stuck because of the limitation of the transmission bandwidth and the refresh rate of the web page. This paper, The Douglas Peucker algorithm is used in system to solve the data transmission of large amount of data delay problem and achieve the transmission of the large amount of data, the overall simulation time of curve in the web page display is decreased, the curves are refreshed smoothly.
Highlights
China's power grid has entered a new period of oversize AC / DC hybrid power grid
The collaborative system for power grid operation mode calculation is based on the calculation data of power grid operation mode, so as to realize the data management
The transient stability simulation can show the changes of the electrical element, but the curve points of the transient simulation are more, and real-time curve transmission is slow, the Douglas Peucker algorithm is applied to the system to solve the data transmission of large amount of data delay problem and achieve the transmission of the large amount of data, the overall simulation time of curve in the web page display is decreased, the curve is refreshed smoothly
Summary
The operation pressure of large number of power electronic components, such as DC transmission, FACTS and so on, the large-scale access of wind power and photovoltaic power supply is increasing, the electrical connection of the whole network is increasingly close, the characteristics of the power grid are changing deeply, and the coupling relationship between the sections is more complex. After the AC and DC hybrid power grid is formed, the interaction between UHV and DC transmission system, the coupling of AC and DC system, the mutual restriction between UHV and UHV system are more obvious, which puts forward higher requirements for the lean and integration level of power system analysis and operation control. The continuous development of complex AC and DC power system and its operation control put forward faster and more intelligent requirements for the calculation of power system operation mode and the analysis and processing of the result. The transient stability simulation can show the changes of the electrical element, but the curve points of the transient simulation are more, and real-time curve transmission is slow, the Douglas Peucker algorithm is applied to the system to solve the data transmission of large amount of data delay problem and achieve the transmission of the large amount of data, the overall simulation time of curve in the web page display is decreased, the curve is refreshed smoothly
