Problems solved by technology

When selecting capacitor bank intervals from the main wiring diagram of the substation, due to the dense main wiring diagrams of many substations, the graphic symbols of the capacitor bank intervals are similar to the line intervals, so it is easy for the on-duty personnel to click on the wrong interval and cause misoperation; on the other hand, the graphical interface of DF8003C is frequently Switching, long operation time, delayed voltage regulation time in case of sudden voltage change, affecting the voltage qualification rate of the entire power grid

Embodiment

[0022] figure 1 It is the schematic diagram of the voltage regulating module of the graphic link of the present invention; the system of the present invention is an improvement to the existing DF8003C centralized monitoring automation system, and the voltage regulating module of the graphic link is set in the described DF8003C centralized monitoring automation system, i.e. monitoring The operating status of the capacitor bank and the module for switching on and off the capacitor bank, the voltage monitoring interface displays as follows figure 2 , when the total reactive power Q of a certain substation shows a positive value, it means that the substation absorbs reactive power to the system, and if the total reactive power shows a negative value, it means that the substation sends reactive power back to the system. When the reactive power shortage of the substation is large, the voltage of the substation bus will be low, otherwise, the voltage of the substation bus will be hi...

Abstract

The invention discloses a capacitor bank switching misoperation prevention system based on DF8003C. The system comprises a DF8003C centralized monitoring automatic system which is internally provided with a graphic link voltage regulating module, i.e. a module which monitors the operation state of a capacitor bank and performs switching operation on the capacitor bank so as to perform switching operation of the capacitor bank in the manner of graphic link jump capacitor interval sub-graphs. The system has advantages of being easy to operate, high in accuracy and time-saving and labor saving so that switching misoperation of the capacitor bank can be prevented to the greatest extent, voltage regulating operation of a monitoring center is enabled to be safer, work intensity of on-duty personnel can be reduced, pressure of work can be alleviated, the psychological burden can be reduced and voltage qualification rate of the whole power grid can be enhanced.

Description

technical field [0001] The invention relates to the field of centralized control automation systems, in particular to a DF8003C centralized monitoring automation system based on a system for preventing malfunctions caused by switching on and off capacitor banks. technical background [0002] With the development of power grid technology and the strict control of human resources by enterprises, the large monitoring mode has become the main trend of centralized monitoring of substations. As an important indicator of the power supply unit, the voltage qualification rate puts forward higher requirements for the large monitoring mode. There are many substations monitored by the large monitoring mode. For the monitoring center that does not adopt the AVC (Automatic Voltage Control) system, the on-duty personnel have to switch on and off the capacitor bank a lot. Moreover, most monitoring centers are rarely equipped with five-proof systems in order to save costs. , which makes the...
