Digital Engineering Ltd is pleased to announce a new contract with TransGrid, an Australian Transmission System Operator (TSO), to model the effects of weather on a section of its overhead line network. DE is an expert in weather simulation, power grid modelling and advanced data analytics. This project will assist TransGrid, which operates the transmission network in the state of New South Wales, to fully operationalise its innovative dynamic line rating system.
DE will utilise a version of its high-resolution Weather Research and Forecasting (WRF) model developed by its team of meteorologists, data scientists, mathematicians, engineers and software developers to allow TransGrid to identify overhead line assets that are either shielded from local weather effects or sit in microclimates.
They will highlight spans which experience weather patterns significantly different from the data gathered at the nearest meteorological station by modelling weather variables such as wind speed, wind direction, temperature and solar irradiance. The results will quantify the accuracy/uncertainty of the weather model data by comparing it to observed historical weather data across the region.
Rob Sunderland, Managing Director for Digital Engineering Ltd said: “Digital Engineering is helping companies understand the past, present and future impact of weather on asset condition and network operations by leveraging our understanding and modelling of both climate and power systems. Advanced analytics is proving to be a powerful tool when managing a network infrastructure and optimising network performance. We are pleased to be supporting TransGrid in its efforts to operationalise its dynamic rating system.”
Hoang Tong, Principal Engineer for TransGrid said: “Accurately determining the impacts of shielding and microclimates on transmission corridors is one the key in unlocking the dynamic capacity and robust design of transmission lines. This is an important aspect for TransGrid going forward, as we augment our transmission network to meet the energy transition to a lower emissions future, without compromising the delivery of reliable and affordable energy to customers”
Once the WRF model is proven on this section of the TransGrid overhead line network then, if appropriate, the process will be repeated for other parts of the system.
TransGrid operates and manages the high voltage electricity transmission network
in NSW and the ACT, connecting generators, distributors and major end users.
Our network is the backbone of the National Energy Market, enabling energy trading between Australia’s three largest states along the east coast and supporting the competitive wholesale electricity market. This allows energy consumers to gain access to the lowest cost generation available.
We strive to create value for our customers and the broader community by providing affordable, safe and reliable transmission services. Through efficient maintenance, proficient operation of assets and prudent investment in our network, we keep more than three million homes and businesses connected to electricity 24/7.
