Research and design on power SUPPLY NETWORK sand table exercise system

The sandbox exercise technology is used in the military field early, on microfilm military topography sandbox system, by repeatedly deduction, strategy and tactics problems can be found on both sides, so the combat capability of the commander can be improved. With the development of the power system, the size of interconnected power system is increasing, power network operation modes is more complex, to analysis and calculate power network stability is more and more difficult, power network stability analysis has special analysis calculation software. However, the development of software support of power system operation mode needs to be more perfect, in particular, convenience in operation mode setting, operation modes change process verification tool, and intelligent comprehensive analysis and evaluation for operation modes are still relatively backward. The main routine work of power system computing and analysis is to check operation mode and operation mode adjustment, the two process is the interactive process: the result of operation mode check is fed back to relevant staffs, directly or indirectly, the next suggestion is provided; relevant staff can also once adjust several operation modes, then the several operation modes is checked in bulk, the remaining work is just to collect results, report writing. This paper will analyse sandbox exercise technology for stability analysis of power system; each basic calculation module is used synthetically, the target operation mode or weak points of the current operating mode can be achieved by artificially repeated automatic deduction or automatic deduction from the sandbox exercise system quickly, automation of operating mode of adjustment and calibration is improved significantly. The sand table exercise technology for power system simulation is based on digital simulation and visual display, so sandbox-style grid analysis operations and show is achieved, the most intuitive services form is provided for dispatchers- comprehensive assessment techniques of sand table exercise system can provide quick calculation of public support automation tool, including automatic seek the power system safe operation limits technology, technology-assisted analysis grid stability, etc. The sand table exercise visualization and interactive technology can provide monitors, large-screen systems, large or small size touch screen display and other types of interactive tools, and interactive operation mode setting and the visual safety assessment results can be achieved.
