Design and Implementation of a Demonstration Supplementary Control System

摘要

The goal of the Chestnut Ridge (Supplementary Control System (SCS) Demonstration Project is to demonstrate how an existing monitoring network, existing air quality models, and existing meteorological forecasting methods can be combined with a control strategy to integrate SCS into electric power system operation. The operation of the SCS is intended to provide field information about air quality, reliability, and economics so that the following technical objectives can be satisfied: (1) to demonstrate that an extensive, sophisticated, real-time monitoring system can be operated at a level of data capture and measurement accuracy sufficient for the needs of an SCS; (2) to demonstrate that air quality can be forecast accurately enough and far enough in advance to be useful in an SCS; (3) to demonstrate that a utility suitably prepared in advance can, in fact, switch fuel, increase stack temperature, and/or shift load while under an SCS so that ambient air quality standards in the vicinity are not violated; (4) to demonstrate that the Control Decision Logic can protect air quality standards while meeting various criteria such as cost and reliability of power system operation; (5) to demonstrate that in the presence of uncertainties in monitoring data, forecasts of air quality, emissions and response time, an acceptable reliability can be proven for the operation of an SCS; (6) to establish that a method can be developed to provide sufficient information to the appropriate regulatory agencies so they can ensure satisfactory SCS performance; and (7) to define the steps required to transfer SCS technology to other sites and plants. Progress is reported. (ERA citation 06:033271)
