Emerson to automate large-scale photovoltaic power project

Technews Industry Guide: Sustainable Manufacturing 2023 Electrical Power & Protection

Emerson will provide advanced automation solutions to help ensure the safety and reliability of New Zealand’s first large-scale solar photovoltaic (PV) power project. This will help solar energy company Lodestone Energy quickly and safely complete its two 23-megawatt sites at Kaitaia and Edgecumbe − an important step in supporting New Zealand’s ambitious goals of achieving carbon neutrality by 2050.

Solar PV – which converts sunlight directly into electrical energy – has become one of the fastest growing renewable energy sources. But efficiently generating and delivering solar PV power requires precise orchestration, integrating a wide variety of third-party systems with automation and control technology to provide operators with intuitive functionality and comprehensive visibility. Emerson’s advanced automation architecture will combine powerful control software and technologies with enterprise data solutions to create an integrated, scalable control solution to maximise output and profitability while simultaneously contributing to grid stability.

“New Zealand’s goal of achieving carbon neutrality by 2050 is an ambitious endeavor that will require many renewable power generation sources to be safely and rapidly brought online,” said Peter Apperley, general manager of engineering at Lodestone Energy. “Emerson’s expertise in automation software for power generation and sustainability will help us more quickly build a world-class facility, while also seamlessly integrating with the national grid to drive successful, efficient operation over the lifecycle of the plant.”

Lodestone will take advantage of Emerson’s Ovation distributed control system and new OCR3000 controller to provide comprehensive control to minimise the impact of variability and intermittency in solar PV power generation. The same technologies will also make it easier for operators to quickly respond to grid frequency events. Ovation enterprise data solutions will provide secure monitoring of solar PV operations from the control room or mobile devices, measuring, monitoring and reporting key performance indicators to increase visibility of plant operations.

“Meeting New Zealand’s renewable energy goals will require power generation companies to rethink the way they operate, democratising data and increasing visibility for everyone across the enterprise,” said Bob Yeager, president of Emerson’s power and water business. “Lodestone’s strategy perfectly aligns with Emerson’s boundless automation vision of an advanced technology stack leveraging integrated, scalable control to provide access to critical data not only across the plant and industrial edge, but also throughout the enterprise.”

Lodestone’s solar PV project requires multiple interfaces to third-party systems, including inverters, high-voltage switchboards, weather stations, site security systems and grid authority remote terminal units. Ovation will act as a process orchestration tool to seamlessly connect these devices to provide fast and intuitive visibility for operators. In addition to providing flexibility and visibility of operations, Emerson’s Ovation platform is ideally suited to support compliance with New Zealand’s energy participation code.

Common power quality factors affecting transformers
Comtest Electrical Power & Protection
Commercial and industrial buildings commonly have a 208/120 V transformer in a delta-wye configuration to feed receptacles. Single-phase, non-linear loads connected to the receptacles produce triple harmonics, which add up in the neutral. When this neutral current reaches the transformer, it is reflected into the delta primary winding, which causes overheating and transformer failures.
