Intelligent substation virtual terminal display method based on Android system

Abstract

An intelligent substation virtual terminal display method based on an Android system is applied to an intelligent substation and comprises the following steps of reading network data of an intelligent substation network; reading IED information; writing correlated information into each IED, displaying current IED graph on one side of a page; searching for all correlated IEDs, displaying the correlated IED graph on the other side of the page; displaying the correlation connection line of the current LED. By means of the method, virtual terminals in the intelligent substation can be displayed in a virtual mode, operators can observe the virtual terminals visually, the limit that a special tool is lacked in the onsite debugging process is solved, and onsite debugging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a graphical display method for virtual terminals of smart substations based on the Android system. Background technique [0002] Smart substation is an important link in the smart grid. It is used to transform voltage, adjust and distribute loads, and cut off faulty lines to prevent accidents from expanding and ensure safe operation. An important feature of the smart substation is that the invisible and intangible optical fiber communication is used to replace the original visible and tangible cable connection, that is, the virtual terminal is used for line control, but because the operator cannot intuitively observe the virtual terminal, this It brings many difficulties to substation operation management and on-site commissioning, so that the reliability of the power grid cannot be guaranteed. [0003] The SCD file of the smart substation is a file in xml format, which is...

Problems solved by technology

Because its main function is to configure SCD software, the overhead is relatively high, so it cannot run on android mobile devices, and there is no search function suitable for debugging sites

[0004] At present, the debuggers of smart substation need to frequently check the virtual terminal connection relationship in the configuration file during the debugging process, and they are often in an outdoor environment where it is not convenient to carry a laptop. Moreover, the SCD configuration tool has relatively high performance requirements for hardware devices and poor mobility. The function is not required by the debugger, the retrieval function is relatively primitive, and the graphical display function is relatively simple. There is a graphical display of the relationship between devices, but there is no graphical display of the logical relationship inside the device.
