System to assess the starting performance of a turbine
First Claim
1. An apparatus to assess the performance of a start of a piece of equipment said apparatus comprising:
- an accumulator to compare a set of on-line data signals corresponding to the starting performance of said piece of equipment to a set of normative starting parameters so as to identify a set of comparison signals;
a risk factor assessor to process said comparison signals and generate quality-of-start prediction signals corresponding to the likelihood of success of future starts of said piece of equipment; and
an anticipator to process said quality-of-start prediction signals and generate output signals, including control signal instructions for future starts of said piece of equipment, for use to improve the starting performance of said piece of equipment.

Abstract
An apparatus and method to assess the performance of a start of a turbine is described. The apparatus includes an accumulator to compare a set of on-line data signals corresponding to the starting performance of the turbine to a set of normative starting parameters so as to identify a set of comparison signals. The comparison signals may also be identified by comparing the set of on-line data signals with a database of historical information relating to starts and design profiles of the turbine. In addition, the comparison signals may be identified by comparing the set of on-line data signals with information in an expert system defining fault conditions in previous starts of the turbine. The comparison signals are processed by an analyzer to identify those comparison signals that exceed predetermined thresholds. Those comparison signals that exceed the predetermined thresholds are processed by a risk factor assessor, which generates quality-of-start predication signals corresponding to the likelihood of success of future starts of the turbine. An anticipator then processes the quality-of-start prediction signals and generates output signals that are used to improve the starting performance of the turbine.
