SVG for EAF compensation —Substation of Fujian Hydropower Plant
Project Background

The 10kV bus of 35kV Jinshan 2 # Substation of Hua'an Hydropower Plant Development Company of Fujian Province is connected with four feeders of Yuxing I, II, III and IV roads for the load of Huayixin Iron Plant, of which Yuxing I and II roads are provided for two sets The electric arc furnace with a capacity of 8000kVA, a refining furnace with a capacity of 4000kVA is provided on Yuxing III Road, and a power transformer with a capacity of 630kVA and a reactive power compensation device of 5000kVA is provided on Yuxing IV Road. During normal production, two electric arc furnaces and refining furnaces will be produced simultaneously.
Because the electric arc furnace will produce a large reactive power shock, it will cause large reactive power changes on the public bus of the grid, and will generate irregular low-order harmonics, which will be generated for the hydropower plant equipment closer to this load. Greater impact. During the on-site feedback of the electric arc furnace, the active power of the hydro generator set fluctuates from 6MW to 7MW. The rapid fluctuation of the active power may cause the unit to vibrate, which is extremely harmful to the long-term stable operation of the unit.

RXPE solution

In order to solve the power quality problems existing on site, RXPE installs a complete set of dynamic reactive power compensation and harmonic control devices (SVG+FC type) with a 10kV direct-hanging compensation capacity of not less than 14Mvar in the user's 10kV switch cabinet outlet, a total of 1 set . The set of devices includes a set of not less than ±7Mvar SVG and a set of fundamental wave compensation capacity of not less than 7Mvar FC. The set of devices can achieve continuous and rapid adjustment of reactive power in the range of not less than inductive 0Mvar ~ capacitive 14Mvar, and control the generation of electric arc furnace Harmonic currents

User revenue

After SVG operation, the grid voltage is stable, the power factor is higher than 0.95, and the power quality problems such as harmonics, negative sequence and voltage flicker are significantly improved.

While the power quality of the grid connection point has been significantly improved, the operating conditions of the user's hydroelectric generator set have also been improved. When the electric arc furnace is working, the active power fluctuation of the hydroelectric generator set is less than 1MW
