Protection early warning strategy simulation operation method for multi-device waveform file transmission

Abstract

The invention discloses a protection early warning strategy simulation operation method for multi-device waveform file transmission. The method comprises the following steps that a data interaction relationship between a plurality of wave recording devices and a protection early warning strategy (executable file) is recorded by using a configuration file; a management host process creates a multi-device ftp service thread, applies for a shared memory for communication with the protection early warning strategy sub-process, forms a protection early warning strategy input demand list, and initializes a device recording file update list; the ftp service thread periodically detects whether a new waveform file is generated by the wave recording device or not, and obtains the latest waveform file; whether the updated file meets the operation requirement of the protection early-warning strategy or not is periodically checked, it is notified that the protection early-warning strategy sub-process that the waveform file can be read, and then the update list is emptied; the waveform file is analyzed, the protection early warning strategy is operated, early warning information is printed, and after operation is finished, the protection early warning strategy sub-process enters the waiting state again till the waveform file updated next time meets the protection early warning strategy operation condition.

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 DC power grid construction and the development of technology, the protection and alarm strategies in DC control and protection devices have gradually matured and solidified. In view of new abnormal situations in operation, practitioners expect to monitor and control new abnormal situations by independently compiling control and protection strategies. early warning. At present, many software tools for compiling control and protection strategies have been used, but most of the control and protection strategies are run in simulation devices, which have problems such as high cost, limited display of early warning information, and inflexible parameter adjustment. Therefore, the protection and early war...
