The case for advanced analytics and remote diagnostics

During the last 25 years significant advancements have been made in remote monitoring capabilities for power plants. A number of operations and maintenance (O&M) functions can routinely be managed remotely, and it is also becoming more common for peaking and renewable energy plants to be remotely operated reliably and safely.

Operating and maintaining a full-scale power plant remotely presents challenges that require sophisticated systems, reliable sensor and diagnostic equipment, stable high-bandwidth communication, and advanced security protocols. Even with progress made in each of these areas, some plant managers don’t foresee a scenario where remote operations will become the norm. But even in cases where there are no plans to run a generating station from a remote location, there is still a solid case for adopting remote technology.

Here are five reasons why the case for remote technology is stronger today than ever before.…

The post Organic Technology New Paradigm for Power appeared first on POWER Magazine.

A Florida-based company that touts what it calls a scalable organic energy-based power technology has launched operations in North America, and said it is making its technology available across several markets including for transportation and commercial buildings.

GO-OPV, LLC on Nov. 17 announced its ORENgE organic technology will be used in a 120,000-square-foot commercial property in New York, where ORENgE panel window installation will provide the property’s power over ethernet, along with meeting the UL 924 lighting standard for emergency lighting and power equipment. The company on Tuesday said it also is accelerating a zero-carbon program for large trucks that will provide vehicles with an advanced low-light power technology.

The technology is part of a growing segment of power generation that includes building-integrated photovoltaics (BIPV), where photovoltaic modules are integrated into a building. The ORENgE technology, in development since 2012, uses a building’s windows as a power generation source.…

Technology for Advanced Asset Inspections

The post Technology for Advanced Asset Inspections appeared first on POWER Magazine.

Netze BW GmbH is the largest distribution system operator (DSO) in Baden-Württemberg, which is the third-largest state in Germany. Netze BW is responsible for high-, medium-, and low-voltage networks across the state. Its power lines stretch over 100,000 kilometers (more than 62,000 miles), and like all power utilities, it faces a constant challenge of monitoring, inspecting, and maintaining the network.

Without rigorous asset inspection, the utility cannot ensure a stable, secure, and safe supply to customers. However, detailed inspection over such a large, disparate area is extremely resource intensive, which creates a tension with the need to control operational costs. Historically, Netze BW has struck a workable balance in this respect; however, times are changing for DSOs.

The Challenge: A Time of Transition

The traditional approach to inspection has been to deploy teams of engineers to manually inspect assets, traveling around the state and climbing utility poles—a job not without danger.…

Flexible Small-Scale Generation Empowered by Once-Through Boiler Technology

The post Flexible Small-Scale Generation Empowered by Once-Through Boiler Technology appeared first on POWER Magazine.

JCE-once-through-boiler-HRSG

Distributed generation integrated with intermittent renewable generation responds to the growing need for highly flexible small-scale (less than 100 MW) power generation resources. The limiting factor facing plant designers is that the conventional heat recovery steam generator (HRSG) does not enable fast-acting power generation demanded by modern grid systems. John Cockerill Energy’s vertical once-through boilers fill this technology gap—combustion turbines are no longer constrained by the slow thermal performance of a HRSG when quick starts/stops, load following, or transient response to grid disruptions are routine. Also, the modular nature of the once-through boiler reduces installed cost compared to conventional field-erected HRSGs.

Cogeneration, combined cycle, and combined heat and power technologies are commonly used in flexible small-scale power installations of less than 100 MW. Developers of these facilities share the common design goal of maximizing plant operating reliability and efficiency while minimizing the lifecycle cost of plant ownership.…

The POWER Interview: Technology Helps Integrate Renewables to the Grid

Patrick Lee, who founded and leads PXiSE Energy Solutions, a subsidiary of San Diego, California-based Sempra Energy, is a proponent of energy sharing. His company builds enhanced grid management systems, using data, insights, and algorithms “to maximize efficiency and reliability of all DERs [distributed energy resources] as one system.” In other words, a PXiSE-supported microgrid is designed to interact with the grid, balancing the supply and demand of power, in an energy-sharing mode, rather than just managing an islanded microgrid.

The company’s Active Control Technology (ACT) platform is used at Sempra’s headquarters in San Diego as well as at other sites, including Con Edison’s 200-MW Great Valley Solar project near Fresno, California; the 110-MW Pima Solar facility in Mexico; and in distribution grids in Australia operated by Horizon Power.

Lee has said PSiXE’s technology provides a cost-effective way for users to move from fossil-fueled power generation to renewables. Lee recently talked with POWER about how PSiXE approaches the challenge of integrating renewable power generation to the grid.…

GE Marks ‘Ultra Low’ NOx Gas Turbine Technology Triumph

In a significant technical triumph, GE has completed first installation of a new gas-fired power plant technology that it says can reduce nitrogen oxide (NOx) emissions to 5 parts per million (ppm). 

GE on April 11 completed combustion upgrades on nine GE 9E gas turbines at five power generation enterprises in Shenzen, a major industrial city in Guangdong Province, China, outfitting them with the company’s newest iteration of its dry low NOx (DLN) solution—DLN1.0+ with Ultra Low NOx. 

The turbines are owned by Shenzhen Nanshan Power Corp., Shenzhen New Power Corp., Shenzhen Datang Baochang Gas Power Generation Co. Ltd., Shenzhen Yuhu Power Co. Ltd., and CNOOC Shenzhen Power Co. Ltd.

The upgrade reportedly reduces NOx emissions from the E-class Chinese turbines from 50mg/m3 (about 25 ppm) to 15mg/m3 (about 7.5 ppm). According to GE, the reductions are achieved through an increase of the flame temperature. “A flame with a lower temperature will produce less NOx, and the key is to be able to mix air and fuel together prior to burning,” it explained.…
