Get a quoteInverter substation - this CSS is made with a concrete or or sheet metal base frame (per market requirements) per the latest IEC standard 62271-202 consists of DC/AC inverters, primary low voltage AC switchboard, step up distribution transformer (oil or dry type) and medium voltage gas insulated or air insulated secondary switchgear.
Substations or “grid nodes” with the strategic integration of high-voltage power electronic converters, discussed from here on as solid state power substations (SSPS), can provide advanced capabilities and facilitate evolution of the electric power system.
For example, harmonics from power electronic converters can lead to unwanted resonances that can influence the operation and lifetimes of other substation equipment. EMI impacts, noise, and overall substation footprint are other facets that need to be considered.
Transformer substations, collector stations and inverter substation meeting the latest global IEC standards up to 24 kV. Solar and wind renewable energy is rapidly growing globally. Power is generated at low voltage DC levels and transformed up to medium voltages for network distribution.
The inverter outputs three phase AC current to a step-up transformer. The step-up transformer outputs to a collector in the substation component, in which flows to the collector arrangement, feeder arrangement and key protection component. Finally, it is fed to the grid at 115 kV.
“Inverters” is the general term for power electronic converters that change DC power to AC power. These power electronic systems are critical to the integration of variable renewable resources and battery energy storage because they enable the electricity generated or stored to be injected back into the grid.
