Dalian United Holding Co., Ltd. launched a power quality analysis management online monitoring system program
On April 15, 2014, Datongda Holdings, a leading electronic component distributor dedicated to the Asia-Pacific market, announced that its company will launch a power line monitoring system based on ADI and Freescale chips. The power industry is a basic industry that affects the national economy and the people's livelihood. How to ensure the safety, reliability, economy and environmental protection of modern power grids has become a global challenge. The connotation of modern power grid includes realizing safe and stable operation mainly to resist accident disturbance, reducing the risk of large-scale outage; making effective use of distributed power supply; improving the efficiency of power consumption and power quality of users; improving the utilization rate of power grid assets, etc. Wait. It can realize on-line monitoring of electric energy, analysis and processing of collected data, and generate various electric energy and power quality reports, analysis curves, graphs, etc., which facilitates analysis and research of electric energy quality management. The inevitable choice of system construction. First, the program features The power quality online monitoring system has GPRS wireless transmission function and Ethernet remote transmission function, which can know the real-time data of each monitoring point anytime and anywhere, and can modify and set any monitoring point at any time through remote control technology. Detection. The recorded data can be viewed at any time and anywhere, and detailed and in-depth analysis can be performed on the host computer. If an abnormal power event occurs, the alarm prompt can be issued at the fastest speed, and the original device can quickly check the device number and the location of the device on the computer. Customers can easily update the monitoring terminal program by remote download and installation. Built-in large-capacity flash memory disk ensures the length of recording time and the integrity of recorded data.
