Application of machine learning algorithms in boiler plant root cause analysis 

It is often difficult to determine the cause of upset or detrimental boiler conditions because the large number of boiler input and output parameters create a complex problem to troubleshoot. Such was the case in this study, where a radiant superheater and internal desuperheater were retrofitted in an existing industrial water-tube boiler at a South […]

Understanding the basics of power measurement theory

Electrical power applications are changing rapidly. LED lighting is replacing incandescent lamps, variable speed motor drives replace directly coupled electric motors, and photovoltaic (PV) installations and wind turbines generate additional electrical power. This means the load on the electric network is changing. More harmonics and more risk of unbalance. This so called “bad” power costs […]

Integrating renewable energy sources into smart grids – Part two

There is global momentum to diversify electricity generation sources for economic, environmental and security reasons. Distributed generation (DG) enables more companies to enter the electricity market stimulating competition, encourages the development of renewable energy (RE) and limits the impact of events such as cyber-attacks. However, conventional electricity distribution networks are poorly matched to the needs […]

The gas turbines/battery hybrid: Ideal partner for wind and solar

The increasing amount of renewable energy in networks has led to challenging situations which require flexible balancing generation plant that can respond rapidly to changes in generation and demand. Open-cycle gas turbines (OCGTs) have been used successfully in this function, but the growth of renewable energy (RE) in some networks has outstripped the ability of […]

Choice of PV backsheet material affects module life

DuPont Photovoltaic and Advanced Materials’ (DuPont’s) 2019 Global Field Reliability Study shows that the choice of backsheet material used on PV modules can result in significant degradation and negatively impact solar module performance. The report lays out failures with PET, polyamide and PVDF backsheets and issues with glass-on-glass modules. The report also highlights trends in […]
