4. An OMS scheduling intelligent analysis method is characterized in that: the method comprises the following steps:
acquiring various real-time or historical data of a 10kV line of a transformer substation;
the heavy overload monitoring module performs the following processing: acquiring real-time data of a three-phase current of a 10kV outgoing line, and storing the acquired data in a distribution network OMS system; comparing and analyzing the 10kV outgoing line three-phase current with data of a distribution network 10kV line CT database; recording overload or overload information;
when the trip data of a 10kV line is acquired, if the trip line is detected to be a power protection line, the generated trip record is matched with the trip accident event grade, and an accident trip grade is generated;
automatically counting the trip times of the 10kV line, matching the counted times with the trip accident event grade except for successful coincidence, and generating the accident trip grade and the trip times in trip information when the trip times of a certain 10kV line exceed the accident grade within 1 month;
after the 10kV line of the distribution network is tripped, calculating the load of line loss according to the acquired alarm message and the current and voltage data, and recording and counting the reason causing the trip after the fault is found, so that a dispatcher can conveniently analyze the problems of the line.
5. A computer system comprising a memory, a processor, and a computer program that is executable on the memory and on the processor, wherein: the processor, when executing the computer program, performs the steps of the method of claim 4.
6. An electronic device comprising a memory, a processor, and a computer program that is executable on the memory and on the processor, wherein: the processor, when executing the computer program, performs the steps of the method of claim 4.
7. A non-transitory computer-readable storage medium having stored thereon a computer program, characterized in that: which computer program, when being executed by a processor, carries out the steps of the method as claimed in claim 4.
