REMOTE MONITORING SYSTEMS WORLD PULP&PAPER 36 The customer’s system is monitored from the ABB Ability Collaborative Operations Centre in Helsinki, Finland. • Software versions • Setting parameters • Nominal values Approximate 10Tb of data is collected annually in this specific case. To optimise use of data storage, high resolution data is stored for three months for troubleshooting and calculation purposes. Minute or hourly averaged values are stored for 20 years as a foundation of future analytics. This long-term history data is more valuable after many years of operations. In case of reliability issues, calculation and comparison of operational and conditions data may be used to avoid future downtime and improve reliability. The main server runs the Real Time Data Base (RTDB) with over 50,000 signals. Calculations are done by the main edge server. The server architecture is virtualised. APPLICATIONS The applications for electrical condition monitoring include a user interface intended to be used by customer technicians or engineers, and by supplier specialists. The interface presents measured and calculated data in useful formats to support daily activities and deeper investigations. • Operations analytics of excessive use of breakers Drives • Environment monitoring for ambient temperatures • Stress calculation to detect conditions shortening key component lifespan • Cooling fan lifespan estimation COLLABORATIVE OPERATIONS The customer’s system is monitored from the ABB Ability Collaborative Operations Centre in Helsinki, Finland. Basic activities performed in the center: Monitoring service – includes daily checks of customer data by ABB specialists. This supplements the customer’s own efforts, and is extended to many customers regionally and globally. Setting up drives and other electrical equipment and systems correctly for each application is the key to guarantee trouble-free operation for the coming years. Comparison and validation of the settings after commissioning are being carried out with recommendations given to fix potential risks. Corrections are applied remotely under an agreed upon safety protocol, or during the next planned shutdown. Safety is always the number one priority when making adjustments to the plant in full production. Remote assistance – provides rapid response support by accessing data in real-time. The local drives service team delivers a one-hour response time where a specialist may connect to the system. Specialists can then guide customers through troubleshooting processes and repairs. Customer spare parts stocks are optimised and available to make fast repairs. By supporting Overview The system overview provides a quick summary of installed equipment status. Equipment details Each type of product has an individual display to show product status, alarms and trends (Figure 5 shows an example of an equipment monitoring detail page). Availability is calculated for each device whilst reliability has product- specific calculations. Examples of monitored KPI’s in the system and on the dashboards: High and medium voltage units • Breaker condition indication based upon the opening and closing times of breakers • Protective health monitoring of protection relays based upon self- monitoring features UPS • Charging and discharging analytics • Battery condition estimation • Battery lifetime estimation Low voltage breakers • Breaker condition index based upon contact wear • Predictive health monitoring of protection relays based upon self- monitoring feature Figure 4.
