The Research And Application Of The Electric Power Dispatch Prevent System Based On The Sap System

Intelligentized Ensuring System for the Whole Process of Dispatching (hereinafter it's called'Ensuring System' for short), which mainly providing service of ensuring the validity of operating writ and working writ to dispatching jobs, basically is made of intelligentized system for writing operating writ based on EMS and writs'administrant system based on SAP. According to experience of dispatcher and rules of operating, this system works by rule and line, clearly, and quickly. At the same time, it collects abundant Real-time datum, making sure state of every equipment showed by the system is correct.The writs'administrant system base on SAPcan manage programs of examine and repair, and ensure the process of operating. When it has read the operating writ written by EMS, the writs'administrant system associates jobs of examine and repair with working writ,according to'Operating Regulations of China Southern Power Grip','Guangdong Province Dispatching Regulations', and so on, In order to safeguard the dispatching operating process.By technology of communication and connection, it sends the operating writs written by EMS to the writs'administrant system newly built on EAI. So the wall between EMS and SAP has been broken, and in some degree a bran-new system ensuring process has come out. Operating writs, working writs and schedule of examine and repair, those three parts get relationship by this system, which solving the problem of ensuring the whole process of operating and working, supplying a gap of domestic software system for ensuring dispatching jobs. It ideally associates the changing state of equipment and jobs appearing on subsection circuitry with many-sided power supply, and forbids false working order, which effectively ensuring operating writs. The percentage of correctness of operating writs can be 100%. The ensuring system is very convenient to write operating writs and get maintenance. Once the system runs, no extra maintenance is required. When great change takes place in correction or equipment, users can avoid large sum of manual work of changing dates and pictures. With advanced software technology and effectual logistic arithmetic, It builds a structure which can expand kinds of functions, That is very agile. Taking advantage of graphical interfaces to select equipment to operate with mouse, and a integrated operating writ is done without input a single word. It makes writing operating writs more expediently and quickly. With the new concept of administrant system of operating and working, the crude conflict between safety and efficiency can be solved in the system with new high tech.None paper using comes true in the system and every operating completely is warded by PC. On data-base control is added to every operating item of the writ, and to the order of every item. Because the order and the item is controlled, sending command, getting command, and reporting result have to be carried out one by one in order. In this way, possibility of missing or skipping operating item is got rid of. Besides, the system realizes kinds of applied function to forbid false operating. What's more important, in the system, there are every part of dispatching which controlled by PC, such as'operating item option','forbidding false operating item','writing operating writs','operating writs'transmission and association'.'examining and approving operating writs','carrying out operating writs',' operating writs'manage and statistic','permission of working writs (beginning and ending)',' working writs'manage and statistic', etc. Those measures not only can ensure the power grip working well, but also enhances dispatching efficiency. As the first system which includes most dispatching jobs and can forbid false operating, when appropriate regulation takes place, it can accommodate with dispatching jobs of internal most area. It's very valuable to spread.
