MODULE DETAILS

Module 19: Monitor and Control Electrical Network

Nominal duration: 5 weeks (60 hours total time commitment)

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

MODULE PURPOSE

This module will examine the components of Supervisory Control and Data Acquisition (SCADA) systems, responding to operation of protection and other alarms, responding to technical and outage-related enquiries from consumers, planning system outages for maintenance work and applying the relevant communication tools available.

2.   Respond to protection operation and other alarms/emergencies

3.   Receive, and respond to consumer enquiries on outages

4.   Plan and coordinate system outages required for network operation and maintenance

5.   Examine and apply relevant communication facilities for network monitoring and control

 

 



Learning Outcome 1

Examine the components of SCADA systems

Assessment Criteria

1.1

Examine and discuss the benefits of SCADA in system operations

1.2

Discuss the different SCADA architectures commonly used in power systems

1.3

Examine and discuss the suitability of IEDs for automation at substation and network levels

1.4

Explain the use of industry standards such as OPC and international standards such as IEC 61850 in achieving inter-operability

1.5

Formulate and interpret typical reports from SCADA


Learning Outcome 2

Respond to protection operation and other alarms/emergencies

Assessment Criteria

2.1

Discuss the typical tripping and emergency alarms from SCADA

2.2

Examine and discuss the response required for alarms with examples (such as transformer temperature or network over voltage)

2.3

Explain the control responses expected if a trip occurs

2.4

Explain the application of system event information such as relay flags, fault indicator signals, ACR lock out etc. to localise a failure and sending out work crews to identify faulty equipment.

 

 


Learning Outcome 3

Receive, and respond to consumer enquiries on outages

Assessment Criteria

3.1

Explain the process of receiving, acknowledging and logging the reports from members of public or consumers about service outage or abnormal events

3.2

Discuss the actions required for problem resolution based on work roles and responsibilities

3.3

Compare the reports with other system-related information (SCADA alarms, trip events) to localise the problem

3.4

Examine the use of:

(a)   drawings and documents

(b)   past events

(c)   weather conditions, and;

(d)   other factors to help understand and react to         reports



Learning Outcome 4

Plan and coordinate system outages required for network operation and maintenance

Assessment Criteria

4.1

Discuss the approach of planned vs. unplanned maintenance

4.2

Explain the need and procedure for planning the activities related to periodic inspection and maintenance

4.3

List and explain the actions required to ensure that the respective equipment is made available for maintenance

4.4

Explain the factors involved in:

(a) deploying work crews, and;

(b) establishing communication methods/procedures        to monitor work progress

4.5

Examine and discuss the reports from work crews after inspection and maintenance, with reference to:

(a) updating of records, and;

(b) initiation of follow-up measures.



Learning Outcome 5

Examine and apply relevant communication facilities for network monitoring and control

Assessment Criteria

5.1

Discuss the various communication methods used

5.2
