Since massive power electronic equipment and Non-linear Load are widely applied in power system, problems of power quality is becoming more and more serious. Power quality is not only against the power system security and power grids stable operation, also launch serious threat to users in power system. Therefore, various electronic corporation had developed power quality monitor equipment and power quality analysis system. Whereas, due to difference of system function and communication protocol between different corporation, cause Electric Power Supply Bureau face a peck of difficulties when they connecting monitor equipment and analysing power grids quality.. The integrate platform in this thesis is based on full analysis of communication protocol and system function in main trend of monitor equipment corporation, come up with a power quality access plan in multiple producers, it is also the base of district power quality analysis. This thesis aims at several key problems related to system framework, made a deep study of multithreading concurrency model, protocol library, Web service communication. Then bring up a solution based on ACE concurrency service units , As well as applied into the design of system framework..This thesis summarize the research background , purpose , content and the structure first, then introduce technical background, including Middleware Technology, ACE Adaptive Communication Environment, Oracle C++ interface(OCCI) ,etc..This thesis also elaborates on the access platform requirements, and use ACE object-oriented technology and reusable software framework, design develop implement a Lightweight general access platform that is Cross-platform,well performing,easy maintenance and transplant, which is able to running in general function host computer and network. then elaborates multiple technologies and key achieved on this platform, including completion port(IOCP) thread pools, Cutting Half Sync/Half asynchronous multi-thread concurrency model, Connection Pool technology, and the implementation of WEB service communication, multiple corporation protocol arsenal and dynamic configuration management services. When the system developed completely through test , combine power quality main station into district power gird and power quality general analysis system. By way of online monitor and professional data analysis in general analysis system, acquainted with the law of pollute of load power quality in power grid operation, find out dynamic time of power quality load and geography distribution status, provide essential data support in power quality analysis ,control and improvement.
