Abstract


As science and technology and industrial development, many users of the high degree of automation increasingly sensitive to power quality . Any power quality problems will lead to a decline in product quality , and even engineering work pause, causing incalculable damage to the user . Improve power quality , reduce network losses , improve equipment life, reduce power production accidents. Power quality is directly related to the overall effectiveness of the national economy , so the power quality in-depth study has very important significance. Power quality pollution control is inseparable from power quality monitoring . Therefore, accurate and complete monitoring of power quality power quality management is one of the necessary means . Relative to foreign terms , China's R \u0026 D power quality monitoring devices is relatively backward . Most domestic manufacturers to adopt the MCU or IPC structure , these instruments compared with foreign advanced technology , the only advantage is the low price, but in practice there are many problems . Therefore, this article uses the current Texas Instruments (TI) company's new ARM DSP dual-core architecture chip OMAPL138 designed a new type of power quality monitoring system, which can not only rely on the powerful DSP to achieve high-speed computing power line monitoring functions, but also can take advantage of ARM and Linux operating systems easily develop interactive interface . The program is highly integrated , low cost, highly cost-effective and market competitiveness, and very suitable for practical industrial product development. Finally, the finished paper prototype was tested , the results showed that: The developed power quality monitoring device hardware and software design is reasonable, reliable data acquisition , algorithms correct the measured results verify the feasibility and reliability.
