Protecting device for automatic remote wireless transmission of data

Abstract

The invention discloses a protecting device for automatic remote wireless transmission of data, which comprises a CPU (central processing unit) module, a logic control module, an AD (data acquisition) module, an analog quantity collecting module, an input / output module, a communication module, a GSM (global system for mobile communications) module, a storing module, a watchdog module, a display module and a power managing module. The protecting device disclosed by the invention can realize automatic data sending, automatic administrator calling of important load faults and Chinese instruction operation; and protecting device disclosed by the invention is characterized by long communication distance, no wiring, low cost, high reliability and safety.

Description

technical field [0001] The technical field of the present invention is: a power system relay protection device, which has the function of automatic remote wireless transmission of data. Background technique [0002] At present, substations and distribution substations in areas with developed economy, dense population, and heavy electricity load are equipped with advanced protection devices, communication equipment, and sufficient personnel. When the relay protection equipment operates, the relevant personnel can quickly know the fault information through the on-duty personnel and dispatchers; when it is necessary to send power to a certain line or reduce the secondary load, the dispatch center can solve the problem by clicking the mouse. For economically underdeveloped areas with sparse population and small electricity load, but scattered electricity load, especially in some areas of Xinjiang, Gansu, and Shandong, the power distribution lines of oilfield power grids have lon...

Problems solved by technology

However, it does not have instructions in Chinese and does not conform to the habits of power system users. When users send control instructions, they need to search for specific instructions, which is troublesome. It does not have a time adjustment order, which is very important for analyzing the cause of accidents in the power system. Important; it can only send the status of displacement, but not the status of voltage, current, and power; it can only send text messages to the management personnel's mobile phone from the protection device, but cannot realize the mode that the management personnel actively inquire; it can only send text messages , if the management personnel are at rest at night, when an important load has a protection action, it needs to be dealt with immediately, and the management personnel cannot be informed immediately; all the management personnel have the authority to modify the parameters, and according to the habit of the power system, there should be only one It is an advanced user, and the others are ordinary users. Ordinary users can only operate circuit breakers and view data
