The invention relates to a distributed online
monitoring system and method for an
electric energy metering device. The distributed online
monitoring system for the
electric energy metering device at least comprises a monitoring subsystem (4) for the
electric energy metering device in a
transformer substation, a customer electric energy meter centralized reading motoring subsystem (9), a monitoring unit (10) for the electric
energy metering device in a metering point and a monitoring center (7) for the electric
energy metering device in a power supply company. Data
abnormality and fault early-warning, error alarming and inspection and
verification request judgment are performed through an on-
site monitoring device; relevant
power grid event information is acquired through a master monitoring
station (6) for the electric
energy metering device in the
transformer substation and the monitoring center (7) for the electric energy metering device in the power supply company to be used for assisting in
decision making; finally, the decision is made through
business personnel. The traditional regular inspection and
verification mode is broken, and the inspection,
verification or maintenance efficiency is high. The communication burden on a monitoring network is reduced, the requirements for a communication environment are lowered, data amount of the master monitoring
station (6) for the electric energy metering device in the
transformer substation and the monitoring center (7) for the electric energy metering device in the power supply company is reduced, and the operation efficiency is higher.
