Graftech
● Situated in Apodaca, Nuevo Leon, Mexico.
● Devoted to the manufacture of electrodes.
● They have been dealing with energy high quality issues.
Findings
● Inductive non-compliance 100% of the time.
● Excessive load variations.
● No compensation gear.
● A comparatively excessive degree of 2nd harmonic is current.
Resolution: Set up of two STATCOMs +/- 10 MVAr every
● One STATCOM was put in for every of the 2 transformers.
● 36 MVA mains (230 – 13.8 KV).
● Quicker resolution for energy issue compensation.
● Energetic harmonic present filtering functionality.
● Much less space required per KVAR.
● Latest and most dependable know-how out there.
Why is STATCOM the perfect know-how?
● Tools responds dynamically to the load.
● Operation of the gear is by energy electronics.
● In comparison with its primary predecessor, the SVC, the STATCOM has a lot increased effectivity and efficiency.
Outcomes
● The STATCOM met the dynamic MVAr demand created by the variable load heart operation.
● A mean PF worth of 0.99 is met 100% of the time.
● Enhancements in energy high quality parameters
● For voltage unbalance, a most worth of 0.171 % was obtained throughout the measurement interval, remaining under the two% restrict established within the Grid Code.
● Present unbalance had a most worth of 4.814 % throughout the measurement interval, remaining under the 15% restrict established within the CoR.
● The values of wierd and even single harmonic elements are inside the limits.
● Harmonic currents have been lowered, highlighting the 2nd harmonic present.
● The utmost THDD[%] worth within the measurement interval was 1.09 %, remaining under the restrict, which for this load heart is 3.75%.
● Flicker values for the ninety fifth percentile Quick Time period Voltage Swing Index (STFI) was 0.382 remaining under the Grid Code restrict of 1.0.
● Flicker values for the ninety fifth percentile Lengthy Time period Voltage Fluctuation (LTI) Index was 0.329 remaining under the Grid Code restrict of 0.80.
Advantages
● Grid code compliance.
● Longer helpful lifetime of plant gear.
● Decrease vitality and upkeep prices.
● Improved course of effectivity.
● Elevated manufacturing capability.
● Monetary bonus from the provider.
