Load flow calculation module is used for carrying out Load flow calculation, and the computational tool of employing is the flow calculation program (pfnt.exe) of DianKeYuan PAD-BPA software package.
Parsing module realizes parsing and the analytic statistics of calculation of tidal current file, dxt graphic file is resolved to the primitive data of specific format simultaneously, and is associated with power flow solutions.
Result display module is used for realizing trend statistic analysis result and visual displaying.
A kind of BPA method of operation power flow solutions analytic method and visualization system, comprise following operation steps:
Step 1: data input module importing data film.Wherein, flow data dat file and geographical wiring diagram dxt file is comprised.Dat file enters parameters validation module, and dxt file directly enters parsing module.
Step 2: parameters validation module is checked the flow data dat file imported, if unreasonable, then returns 1, needs importing data film again; If rationally, by dat transmitting data file to Load flow calculation module.
Step 3: Load flow calculation module is called PSD-BPA software package flow calculation program pfnt and carried out Load flow calculation, and destination file is passed to parsing module.
Step 4: parsing module carries out parsing and analytic statistics to power flow solutions file, resolves simultaneously, is associated by pel with analysis result, and result is passed to result display module to geographical wiring diagram dxt file.
Step 5: result display module is shown result, the statistic analysis result and the visualized graphs that comprise power flow solutions show two parts.
The invention has the beneficial effects as follows the automatic parsing and analytic statistics that achieve BPA method of operation power flow solutions, and show in visual form, work about electric power person intuitively can obtain paid close attention to power flow solutions information rapidly, avoids numerous and diverse text screening operation, significantly increases work efficiency.
Accompanying drawing explanation
