With the increasing development of the national economy and the continuous improvement of people's living standards, the society has higher and higher requirements for the quality of power supply
.
Due to the large area affected by transmission network failures, power grid enterprises usually pay more attention to the automation construction of
transmission networks.
In view of the fact that the construction of distribution automation lags behind, carrying out the construction of distribution automation is the key direction
of the State Grid Corporation to solve the problem of "weak power grid".
To this end, in 2011, the State Grid Corporation of China established a series of technologies, tests and construction standards based on passive optical network technology (PON technology), paving the way for large-scale construction of distribution network communications, and various places have successively carried out distribution automation construction
.
The reason why PON technology is chosen is because the networking structure of PON technology has a high degree of matching with the primary grid frame of power distribution, and the primary grid frame often has single-ray, tree-shaped, ring and other forms, and PON technology networking naturally adapts to these networking forms
.
The reliability of PON is also very high, any optical network unit (ONU) failure will not affect the surrounding ONU, multi-point fault will not cause "communication island", especially PON technology hand-in-hand networking is perfect for the distribution ring architecture
