Functional splitting in multivendor HVDC grid protection
IET conference proceedings., vol. 2025, pp. 355–361
Abstract
Moving towards truly multivendor HVDC grids requires definition of the functional performance at the system and device level, as well as decision making on control and protection architecture. While many technical solutions to solve protection system challenges have been developed and demonstrated in the past decade – e.g. DC circuit breakers and protection relays – there is still no consensus on how to divide the required functionality across different physical devices. This is particularly of interest for multivendor systems, in which well defined functional requirements must be developed for the individual devices and their interfaces. This paper examines a method to perform the splitting of protection system functionality, enabling systematic rules to be applied when choosing a protection system implementation in a multivendor system where different parties have different interests. Behavioural or functional modelling of the system, e.g. using Model Based Systems Engineering (MBSE), is applied to describe the system and enable choices in splitting of functionality between different physical devices and/or devices from different manufacturers.
