Study on an intelligent cooling control method of transformer

Abstract

With the implemeGEPI-173ntation of unattended and intelligent substation, the operation and maintenance personnel are far away from the substation. The cooling system lacks real-time monitoring, fault prediction, remote control and other functions. The number of transformer non-stop caused by cooler fault is further increased, which directly threatens the power grid security. In order to solve the above problems, a new intelligent air-cooling control method is proposed. Based on the large-scale signal acquisition method, a new intelligent air-cooling system design scheme is proposed. The characteristics, hardware system design, software system design, main program design, oil temperature control design, comprehensive switching design, data sharing center design message flow design and other key links of the new intelligent transformer cooler control system are introduced in detail. The results show that the scheme can better meet the needs of unattended substation and realize the intelligent operation of substation. It can further improve the security capacity of transformer production and play an important role in the construction and development of smart grid.
