Together with the present situation of Chongqing power grid flat management, Chongqing power grid has completed the construction of dispatching automation for the area of the southeast and northeast of Chongqing, because of perfecting the “Big Run” system. In the process of construction, the traditional way of data to demonstrate, such as the window of the matters, the typical report, has been unable to meet the requirements of scheduling, monitoring person, with the increasing station and more and more information for monitoring. Therefore, the regulation of visualization technology and grid data analysis technology based on multi- theme, multi-dimensional is introduced to crossed jurisdictional integration system and the concept of regulation of multi-dimensional visual monitoring is put forward to meet the need of the integration of large-scale power grid monitoring. According to the professionals focusing on regulating the business information, the system can provide a scientific means to stabilize bus voltage, analyze the power flow and monitor the power supply redundancy. By the application of the multi-dimensional visualization technology, the safety level of power grid control is improved effectively.
