Latest fire protection requirements for grid-connected inverters in communication base stations

📌

What are the requirements for passive fire protection systems for offshore substations?

Proper equipment spacing, equipment location, and separation of redundant systems should be considered. If provided, proper containment sizing and appropriate drainage should be considered. Passive fire protection systems for offshore substations should follow the guidelines set forth in DNV-ST-, NFPA 850, and IEEE 979.

📌

What are the current needs in modern grid codes?

In Ref. , the current needs in modern Grid codes of different nations are compared, debated, and assessed to satisfy the significant photovoltaic power plant integration. Usually, standards allows the use of devices for system protection from dangerous conditions, such as unwanted islanding.

📌

Which inverter settings should be approved by the company?

settings shall be approved by the Company. IEEE compliant and UL- certified18 inverters shall be equipped with an internal active anti-islanding scheme, under voltage (27), over voltage (59), under frequency (81U) and over frequency (81O) relays.

📌

Can a substation fire suppression system be considered a risk mitigation tool?

If a fire protection system is determined to be accepted as a risk mitigation tool, the literature offers additional guidance for design and installation of an offshore substation fire suppression system. DNV-ST- provides fire protection requirements relating to fire mains (standpipes and hydrants) and deluge systems.

📌

What is an inverter based resource (IBR)?

, a conventional (or legacy) GFL inverter’s control1The term “IBR” is defined in IEEE Std - as an inverter-based resource c nnected to a transmission or sub-transmission system. For purposes of this document, an IBR is taken to mean an inverter-based resource con ected anywhere in the system, including dist

📌

How do I use communication technology to support grid requirements?

Applying the appropriate communication technology to support grid requirements depends upon many factors beyond just the communication technology, how it is deployed (e.g., architecture) and operations. One method is to start with the grid services or processes needing support.
