Description

Technical Field

[0001] The utility model relates to the technical field of the overall adjustment and installation of a synchronous condenser, and specifically discloses an overall adjustment and installation device for a synchronous condenser. Background Art

[0002] In a power system, a distributed synchronous condenser specifically refers to a highly integrated small-capacity synchronous phase-shifting device arranged in a new energy power station, which is used to strengthen the voltage support of the near-end system at the sending end and has excellent transient and steady-state characteristics and reactive power regulation capabilities. The distributed synchronous condenser is mainly used in the power system to improve the efficiency and quality of the power system. By realizing functions such as distributed energy storage and power regulation, it can reduce power transmission losses, improve power quality, and solve the problem of grid-connected operation of new energy power generation.

[0003] After the overall machine test of the synchronous condenser in the manufacturing plant, the concentricity between the rotor and the stator of the synchronous condenser is adjusted. Then, the rotor and the stator of the synchronous condenser are directly packed into boxes and shipped to the user as a whole machine. When installing on-site, complex installation processes such as threading the rotor on-site and finding concentricity can be omitted, greatly shortening the installation period of the unit, reducing the cost of the power station, and improving the operation reliability of the unit; the process of removing the rotor after the overall machine test in the manufacturing plant can be omitted, saving the manufacturing period of the synchronous condenser; the rotor and the stator of the synchronous condenser are packaged as a whole, saving packaging costs.
