𝗭𝗚𝗥 𝗜𝗦𝗟𝗔𝗡𝗗𝗘𝗧, a weak grid detection system (island detection)

The differential elements of the 𝗭𝗚𝗥 𝗜𝗦𝗟𝗔𝗡𝗗𝗘𝗧 system are:

• Non-intrusive system that avoids the commonly used method of positive feedback of a system variable (frecuency or voltage) which causes instability and negatively impacts grid quality.

• It does not affect power factor & does not affect harmonic distortion.

• Provides very low uncertainty in islanding detection, due to the significant difference in impedance between the load and the electrical grid.

• The active power output is non-pulsating under unity power factor (Ø=0), which is the standard operating condition, and only sighty pulsating under other power factor angles (when generating reactive power), improving the utilization of solar cells.

• It enables parallel connection of equipments (inverters or BESS) to enhance the robustness and stability of weak or isolated grids generated by third parties, without compromising their stability.

This system is patented by ZGR Corporación.
