【Abstract】 With the development of the technology of Smart Grid, it brings new challenges to the modern power grid about integrated dispatch and control technology by the State Grid’s reformation under the model of "Big Run" and "Overhaul". The research and application on the smart support system to prevent misoperation and epitomize the ability of control center which can schedule and monitor large grids, and guarantee the security, quality, economical operation and optimal allocation of resources in a wide range.This paper analyzes the current status of regulatory system and sub-station monitoring system. It also studies the business integration of the control center for the integrated system of scheduling and monitoring. Based on D5000platform, this paper studies the maintenance mechanisms about the integrated system of graphics, databases and models, and combines the desigh ideas and remote operation, then builds a workflow model of the remote operation so that the integration and information sharing can be applied in regulation and error prevention of superior and subordinate. This paper includes the following aspects:(1) The research has been studied on the business integration of scheduling and monitoring of power grid, for the first time achieved the objective of real-time online control through the entire process in the operation of regulation, error prevention and verification.The business integration idea has been proposed about the integrated system of scheduling/monitoring, instruction tickets, operation tickets, error prevention and verification. Based on D5000platform, this paper studies the maintenance mechanisms about the integrated system of graphics, databases and models, and combines the design ideas and remote operations, then builds a workflow model of the remote operations, and for the first time achieved the objective of unified management of the entire process and real-time online control of process management of a series of applications. Having the purpose of compressing management levels of remote operations, the production efficiency and the level of security controls is increased.(2) Based on the extension theory, the knowledge base of operational rules and error protection rules are developed in this paper. The technology of intelligent switching deduction which is based on the model of rhombus-thinking, error protection, and AI reasoning is also presented.This paper studies the smart technology of operation tickets and analysises the characteristics of traditional knowledge representation and reasoning mechanism based on the expert database. Through the study of extension theory, the model of power grid which is based on the standard IEC61970as a physical object, a knowledge base which includes knowledge scalability of regulation principles, operation rules and habits is developed. It can use the logical primitives for reasoning and modeling according to rhombus-thinking. The base also designs a feedback inference engine to drive the reasoning model. Thus, the complex problems and contradictions which inherently exist in the rule reasoning of scheduling instruction tickets and monitoring operation tickets are solved. Compared with the conventional methods which use program code to achieve the technology of operation tickets, the extension deduction techniques can solve the problem of diversity and unevenness in different areas and applications.(3) For the first time realized the intelligent interaction among human, machines and tickets.By using the obvious feature terms to segmentate algorithm preferentially, it has to segmenttate the operating instructions of regulatory into a collection of all kinds of words, and then forms the entity object. By using semantic model to match exactly the parsing can be made more accurate.(4)Study on the theory of analysis of error protection, build up expert knowledge base of error protection rules and realize intelligence derived type network error protection topology.This paper expounds the theoretical basis of intelligent topology error prevention, set up the model of power system error prevention and implements the grid connection mode and the intelligent recognition of equipment running status. It also provides an error protected rule inference implementation method based on artificial intelligence and applied it to the control instruction error calibration and remote control operation. By means of analyzing the characteristic of the grid equipment dynamic and static topology relationship and adopting the principle of error analysis algorithm and automatic generation technology of standing between the false logic, an intelligence derived type network topology error analysis function is realised. (5) Combining with service characteristics of control error protected and the IEC60870-5-104specifications, the communication standard of error protection between the master station systems is standardiged for the first time.By means of extending IEC60870-5-104specifications, the remote control error protected information and logical rules interaction mechanism is realiged. Through research and application of error protected master station standard specifications of communication, is established. The information check standard mechanism between error protected master station. Realize the information interaction between error protected master station system models, the only operating right and logical rules are realised.(6) Realize the "source side maintenance" of error protected master station logicThe difference of figure modulus according to regulate error protected master station system is studied. Based on model-driven parsing techniques and configurable semantic conversion method, realize the active call and update of logic formula and parameters of error protection are realised. The logic rule base of error protected master station, reduce the maintenance work, eliminate the safety hidden trouble due to the logic inconsistency of error protection are automatically generated.(7)It is the first time to put forward wide-area file transfer mechanism used for remote control operation management system. The integration framework for data transmission, realize data interaction of "Longitudinal, transverse to the edge" is also built up.The wide-area file transfer is in the file way for data transmission which provides standard interface for the synchronization library data and relationships in a flexible way. It meets the interaction of different application requirements. It can implements information sharing of the EMS system and OMS system across the security isolation devices; It also implements the province and the information sharing. This support system operation strongly improves the automation level of production scheduling management.更多还原
