Method and system for monitoring electric energy quality

Abstract

The invention provides a method and system for monitoring electric energy quality and relates to the technical field of electric power monitoring. The method comprises the steps that monitoring data of electric energy quality information is received, and the monitoring data is stored into a database in a classified manner after analysis and processing of the monitoring data; shared data areas are established for the monitoring data of different types in the database respectively through a memory mapping document manner, wherein the shared data area is established correspondingly for the monitoring data of each type; and a user request sent by a client side browser is received, the monitoring data in the shared data area is read according to the user request, and the read monitoring data is returned to the client side browser in the form of an HTML web page. According to the invention, the client side browser can acquire a Web full pager more quickly; accurate time of the Web page can be greatly reduced; an electric energy quality monitoring terminal task can be optimized; and in addition, dynamic refreshing of the HTML page can be achieved, and a user can carry out online testing and maintenance.

Description

technical field [0001] The invention belongs to the technical field of power monitoring, and in particular relates to a method and system for monitoring power quality. Background technique [0002] The voltage, current or frequency deviation that causes the user's power equipment to not work normally, and any power problem that causes the failure or wrong action of the electrical equipment is a power quality problem. Power quality is usually measured by indicators such as voltage deviation, voltage fluctuation and flicker, public grid harmonics, three-phase voltage unbalance, frequency deviation, temporary overvoltage and transient overvoltage. With the development of science and technology and the national economy, people's demand for electric energy is increasing day by day, and at the same time, the requirements for electric energy quality are also getting higher and higher. Therefore, the power sector and users pay more and more attention to the quality of electric energ...
