Embodiment Construction
[0024] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 As shown, the present invention provides a method for realizing wave recording of channel dynamic configuration, comprising the following steps:
[0026] Step S100: In the initialization stage, the system collects all signal information, and generates an online wave recording configuration table according to the static wave recording configuration;
[0027] Here, signal information includes signal name, signal description, signal address, and signal type; among them,
[0028] The signal name is the unique identifier of the signal in this system, usually a character string, such as "Bay1.Ia";
[0029] The signal description is a character string, which can be in Chinese or other languages, such as "I interval A phase current" or "Bay1_Ia";
[0030] The signal address is the memory address of the signal;
[0031] T...

The invention discloses a wave recording realization method of channel dynamic configuration. The method comprises the following steps: at an initialization phase, a system collecting all signal information, and according to static wave recording configuration, generating an online wave recording configuration table; at an operation phase, tool software firstly reading a current wave recording position and then sending adjustment commands of increasing and decreasing wave recording channels to the system; after the adjustment commands of the wave recording channels are received, the system dynamically modifying the online wave recording configuration table and performing data caching according to new wave recording configuration; and when wave recording trigger conditions are satisfied, the system automatically generating a wave recording file comprising new signals. The method can dynamically modify the wave recording configuration in an online mode, increases or decreases the wave recording channels, realizes real-time effectiveness, improves the flexibility of a wave recording function and improves the development efficiency.
Description
technical field [0001] The invention relates to the realization technology of power system fault disturbance recording, in particular to a method for realizing wave recording with channel dynamic configuration. Background technique [0002] In order to accurately analyze the dynamic process of power system faults or disturbances, fault recorders and relay protection devices need to record the electrical quantities of electrical equipment in real time, including analog quantities such as voltage and current, as well as switching quantities such as the position of circuit breakers and knife switches. It is saved in the standard COMTRADE (common format for power system transient data exchange) file format, which is used for post-event fault process analysis. The usual method of wave recording is that the device will solidify the signal that needs to be recorded and monitored in the program code or write it into the wave recording configuration file. After the device is started,...
