Embodiment Construction

[0020] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Taking a local area network composed of one host PC and two fault recorders as an example, the executable program of the protection and early warning strategy in the host PC is represented by policy.exe. A protection warning strategy simulation operation method for multi-device wave file transmission is realized as follows: figure 1 shown:

[0021] 1) Before starting the main management process, configure the data interaction relationship between the wave recording device and the protection and early warning strategy. The content is stored in the configuration file. The content of the configuration file includes the IP, user name, password, and waveform of the two wave recording devices. The file path and the path of the waveform file stored by the upper PC, also include the protection warning strategy path of the upper PC and the storage path...

Abstract

The invention discloses a protection and early warning strategy simulation operation method for multi-device waveform file transmission. The shared memory for communication between threads, application and protection warning strategy sub-processes, forms a protection warning strategy input requirement list, and initializes the device recording file update list; the ftp service thread periodically detects whether a new wave file is generated by the recording device, and Obtain the latest wave file; periodically check whether the updated file meets the operation requirements of the protection warning strategy, notify the protection warning strategy subprocess to read the wave file, and then clear the update list; parse the wave file, run the protection warning strategy and print the warning information, After the operation ends, the protection warning strategy subprocess re-enters the waiting state until the next updated wave file meets the protection warning strategy running conditions.

Description

technical field [0001] The invention belongs to the field of DC control and protection simulation, and in particular relates to a protection and early warning strategy simulation operation method of multi-device waveform files. Background technique [0002] With the advancement of the construction of the DC power grid and the development of technology, the protection and alarm strategies in the DC control and protection devices have gradually matured and solidified. For the newly emerging abnormal conditions in operation, practitioners expect to independently compile control and protection strategies for new abnormal conditions. Warning. At present, there are many software tools for compiling control and protection strategies, but most of the control and protection strategies are run in simulation devices, which have problems such as high cost, limited display of warning information, and inflexible parameter adjustment. Therefore, the protection and early warning strategy n...
