SVG reactive power compensation cabinet dynamic reactive power compensation 35 kV static synchronous compensator

Description :

　　The SVG dynamic reactive power compensation device adopts electric energy conversion technology to meet the grid connection requirements. China has a relatively large proportion of reactive power line losses throughout the year and consumes a significant amount of electricity. The SVG reactive power compensation cabinet sends inductive current and capacitive current into the power grid for compensation. Controllable silicon capacitors are used to freely control switches, absorb electrical energy in AC voltage systems, and charge DC capacitors. The entire device is designed strictly and has strong environmental adaptability, effectively solving the problem of current and voltage harmonics in the distribution system. SVG static synchronous compensator is currently the solution in the field of reactive power control. The SVG reactive power compensation cabinet can achieve bidirectional adjustment of output capacity and fast response. Global power is developing towards high-power grids. SVG reactive power compensation is widely used in wind and photovoltaic power plants to stabilize and control grid voltage by regulating reactive power output. SVG high-voltage dynamic reactive power compensation can generate and absorb reactive power in photovoltaic power generation. The comprehensive compensation of SVG for large capacity wind farms has a significant effect on overcoming output power fluctuations. The comprehensive harmonic control effect is good. No need to worry about harmonic generation and system resonance.

　　SVG dynamic reactive power compensation cabinet model description: S is the number of three-phase compensation phases; Sometimes encountering single-phase D; H: chain color; KV: Voltage level; Kvar: Equipment capacity; SVG: High voltage static dynamic reactive power generator; At the same time, each enterprise will add the company code when the product leaves the factory, and the New Hundred special code is XBT. SVG dynamic reactive power compensation cabinet is commonly used to solve harmonic hazards in power grids, such as reactive power compensation in photovoltaic engineering, flicker compensation for heavy load voltage fluctuations in electric arc furnaces and calcium carbide furnaces, etc. From the perspective of governance effectiveness, the goal of reducing consumption has been clearly achieved. The core of SVG static dynamic reactive power generator is high-power inverter, and the overall control adopts self commutation phase converter to control the voltage magnitude and phase. The converter determines the output properties of reactive current based on the high and low of the base voltage and AC power supply voltage. Reactive power and active power are freely converted and relatively stationary. When encountering harmonic problems, users should discover and determine the problem in time, and then decide how to choose compensation methods. After all, the SVG dynamic reactive power comprehensive compensation system is carried out with the construction of the entire project.

　　The SVG high-voltage dynamic reactive power compensation cabinet is divided into a series of high-voltage reactive power compensation devices with a rated capacity of 1-100Mvar. The commonly used voltage levels are 6KV, 10KV, 35KV, 6KV, and 10KV. The optional capacity for the 35KV series is 500-1000kvar, and the optional capacity for the 35KV series is 2000-5000kvar. The overload capacity ratio is as high as 120. The capacitance type and induction type automatic continuous stable adjustment can not only be operated separately, but also support multi machine grid connection operation, multi busbar integrated reactive power compensation, and complete safety protection. High outdoor and indoor protection levels. The fault protection functions of the water cooling system, overvoltage, overcurrent, and output communication system provide limited protection for power safety. SVG high-voltage dynamic reactive power compensation device is an active large-area filtering compensation device. At the beginning of the start-up phase, self-excited start-up technology was specifically adopted, fully considering the influence of start-up current, and PLC was added to switch and control multiple capacitor banks. The control method can be selected and set according to the grid problem. The technical parameter values can be set on site and have a multifunctional display interface in both Chinese and English. Backup all data information related to the operation of the power grid for timely adjustment and inspection.
