Since we have built a Predictive Monitoring & Diagnostic(PMD) center and adopted a new predictive maintenance system, we increased synergistic effect of the three major systems. Although we have been thoroughly implementing periodic planned preventive maintenance and preventive inspections, the predictive maintenance system helped us to find minimal changes in the process in advance, and has contributed to reducing losses due to unplanned equipment failures. From October 2014 to March 2017, threes solutions found 144 abnormal events, and we was able to see a savings of approximately $6 million for our operational and maintenance costs. We wish to share and spread the experience in Yeongheung Thermal Power Plant widely and to help the cost saving in the same industry of world by efficient use of the integrated predictive diagnosis monitoring system.
