Fully Automating HRSG Feedwater Pumps
Even a relatively simple start-up process can have many steps and delays for operator cross-checks. Automation can simplify the procedure for the operator while reducing start-up time. In addition, more sophisticated controls techniques may be applied to improve process stability, reduce energy usage, and increase operating flexibility. Modern distributed control system (DCS) platforms offer capabilities that were unavailable just a few years ago. Features such as integrated graphical engineering environments, simplified sequencing controls, and improved human-machine interfaces (HMI) make higher levels of automation more practical from the standpoints of implementation, maintenance, and ease of use. The timing of these advances couldn’t be better—critical operating personnel throughout the power industry are approaching retirement age, and there are insufficient numbers of skilled younger personnel to replace them. Leveraging the existing plant knowledge base to design automation that reduces the burden on plant operators will be essential to meeting tomorrow’s plant demands. As an example, the following case study describes automating a simplified feedwater system for a combined-cycle power plant. The existing legacy DCS controls are proven and reliable; however, the sequence of operations and coordination of regulatory controls is not automated, therefore, it requires a high degree of knowledge and attention on the part of the operator. This case study describes a combination of controls automation strategies and HMI techniques designed to increase the overall level of automation while improving ease of use by operators and maintenance personnel.

Are Flexible Generation Plants Performing as Expected?
This article reviews the performance of the Siemens Flex-Plant installed at the Lodi Energy Center in Lodi, California. Designed to be highly flexible, fast-ramping and fast-cycling to complement renewable power generation, the facility experienced 380 starts over the two-plus year period from November 2012 to January 2015. The consensus is that the facility has lived up to expectations, although operational and maintenance costs are higher than for a typical combined cycle plant.

Gas Turbine Technologies for the Transition
About 60 GW of coal-fired generation in the U.S. will be retired by 2020 and about 35 GW of nuclear capacity will be retired by 2025, according to recent projections by Black & Veatch. Much of that capacity will be replaced with power produced by low-cost, cleaner-burning natural gas. This article reviews the installation of Siemens new FlexPlant technology at the El Segundo Energy Center in California and GE’s new H-class turbines at the Riviera Beach Energy Center in Florida.

VFD at the Hainan Yangpu 220 MW GTCC
This paper discusses the application of variable frequency drives (VFD) in the high-pressure water feeding system of boilers serving Units 11 through 13 of a combined cycle section of the Hainan Yangpu Thermal Power Plant. The article is written by the plant engineer responsible for the operation and maintenance of the system. In the first year of operation there were severe problems with the valve caused in part by inability to measure the outlet pressure of the BFP system and it was determined that a solution lay with replacing the hydraulic coupling with VFD.
