Research On A New Integrated Tuning Computing Platform Based On Cloud Computing Model

As the first line of defense,relay protection is an important guarantee for the safe and stable operation of power system.In order to meet the requirements of sensitivity,reliability and selectivity of relay protection devices in power system,setting accurate and reasonable relay protection value is a necessary condition for safe and stable operation of power network and reducing the damage degree of fault equipment.At present,with the continuous expansion of power system network,the continuous expansion of system setting scale and the continuous development of UHV technology,China has gradually formed a complex interconnected cross-regional power grid pattern.The setting calculation of relay protection in large power network involves a large number of fault operations and However,the current setting computing software has limited computing power,so it is difficult to meet the needs of integrated and intelligent setting computing,so the use of cloud computing will become the focus of the new generation of setting computing software research direction.Based on the combination of power system relay protection setting and cloud computing,this paper introduces cloud computing into power system setting computing,co-ordinates power system intranet server,builds application platform of integrated setting computing system with B/S structure and private cloud mode,and uses computing task splitting technology to split large-scale setting computing tasks into minimum particles.Through task proxy server,we can allocate computing tasks reasonably,receive receipt,call cloud server computing pool for fault calculation,realize cloud setting computing method,and develop intelligent function of setting computing business,Building a New Model Based on Cloud Computing Volume setting calculation cloud platform.This platform is applied on the provincial and local integrated setting platform of Liaoning power grid.The application results show that the setting calculation speed of the system is improved significantly,and the intelligent function developed can improve the working efficiency and reduce the setting errors.And has the hardware intensive,the maintenance is convenient,the interactivity is strong and so on.Finally,the prospect of integrated tuning calculation is prospected.
