the network publishing subsystem establishes a standard Web site in a security zone III so that a user of the non-centralized management system can obtain information published by the system by accessing a Web server through a browser tool according to different authorization levels; the network release comprises two aspects of data transmission of a real-time system and a Web subsystem, namely Web subsystem information synchronization and Web subsystem information release:
(1) web subsystem information synchronization, including:
1) synchronizing power grid model data;
2) synchronizing the picture and the report file;
3) synchronizing real-time data, including system operation condition and fixed value information;
4) synchronizing historical data, including events, alarm information, fault information brief report and wave recording files;
(2) web subsystem information publishing, including:
1) preventing access by unauthorized users;
2) setting different levels of access rights for users with different rights, providing different data, pages, graphs and functions, and setting the maximum number of concurrent users;
3) displaying the power grid operation data, pictures, reports, curves and charts issued by the system;
the support management subsystem comprises a fault analysis module, a report statistics module and a permission management module;
the fault analysis module is used for recording the time of action and the original of the action in real time when the safety and stability control device acts, acquiring the wave recording data sent by the device, reading the wave recording data file, and analyzing the waveform of the electrical quantity and the outlet condition of the corresponding device in the fault process, wherein the wave recording data sent by the safety and stability control device is represented by an effective value;
the report counting module counts the running condition, the abnormal condition and the action condition of the safety and stability control device and makes a report; the data of the report can be from real-time data, historical data, application data, user-defined data and other report outputs; the produced report forms are called, browsed, regenerated and data modified by all workstations of the system or are released on the network; grouping and classification management of the report forms are supported, and meanwhile, modification of data in the database is automatically reflected in the report forms to generate new report forms;
the authority management module configures different authorities for different users, and only authorized users can perform corresponding operations; recording the modification of each authority or content, including recording a modifier, modification time and modified authority and content; the configuration authority specifically comprises the following steps:
the personnel configuring the scheduling operation authority can set the device state and the channel state between the devices and check the fixed value of the safety and stability control device;
the personnel configuring the remote operation authority can set the device state and the channel state between the devices, and remotely modify the fixed value of the safety and stability control device by inputting a password;
personnel configuring automatic maintenance authority can modify the definition of the picture, the database and the database connection definition of the picture foreground on line.
