Digital Simulation Techniques And Implementation For Power Quality Data

With the rapid development of modern communication and network technology, functionality and performance of electronic equipment and products have become increasingly demanding electronic equipment power supply performance requirements are more stringent. In the interests of users and businesses to promote the national electricity sector of the State Grid and China Southern Power Grid power quality requirements are gradually strengthened, whether it is well-known universities or to some of the large power companies and Electric Power Research Institute in the development of performance stability. to minimize the distortion of the electric power transmission power quality smart power analysis equipment to achieve accurate real-time power quality analysis.This topic is on how to improve the level of power quality monitoring and analysis as the core R&D work done, using the idea of modeling of power quality data, such as the flicker of modeling, the amount of actual power transmission through modeling in the form of their use of computer programming. simply is a form of writing software to analyze power quality problems actually encountered.First in-depth study of domestic and international power quality analyzer R&D status quo level, according to the actual needs of the subject, in the Jiangxi Electric Power Research Institute has done a thorough understanding of power quality tester to focus on the actual power transmission data acquisition and classification.Finally, the coding of the software system development system environment using the Microsoft XP system, using VC++language and development environment using MFC Microsoft Foundation framework. Power quality samples will be used PQDIF storage and reader of PQDIF is to describe a logical structure of the power quality indicators. Waveform output module using the GDI image interface, interface API is rich and practical, easy to maintenance personnel to maintain and upgrade the system.
