The invention discloses a distributed 
line loss determination and 
power grid monitoring equipment and method. The equipment comprises a main 
server, at least one second-level 
server connected with the main 
server and at least one third-level server connected with the second-level server, wherein the third-level server is at least connected with an external user terminal, the third-level server comprises an acquisition 
chip, a third-level metering module, a third-level memory, a third-level 
processing module and a third-level communication module, the second-level server comprises a second-level metering module, a second-level 
processing module, a second-level communication module and a second-level memory, and the main server comprises a communication module, a metering module, an analysis module, a monitoring module and a main memory. Data of the 
power grid can be conveniently acquired through three-
level design, a 
line loss value can be acquired through calculation on the basis of the acquired data, the data is accurate, calculation is rapid, an abnormal data area can be found out through comparing an actual 
line loss value and a theoretical line loss value, an overhaul and maintenance instruction can be timely emitted, and 
power grid operation stability is improved.
