MODULE DETAILS

Electrical Network Controls DEPMCN618

NOMINAL DURATION IN HOURS

60 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

This module covers 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.

MODULE PURPOSE

The purpose of the module is for participants to gain fundamental knowledge of processes for controlling an electrical network.

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

5.   Analyse and apply communication techniques for network monitoring and control

LEARNING OUTCOMES

ASSESSMENT CRITERIA

Learning outcomes specify what students will be able to do as a result of the learning.

Assessment criteria provide the criteria by which achievement of the learning outcomes will be judged.

1

Explain the components of SCADA systems

1.1

Explain the benefits of SCADA in power system operations

1.2

Outline different SCADA architectures commonly used in power systems

1.3

Explain 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

2

Evaluate effective ways of operation protection and other alarms/emergencies

2.1

Outline tripping and emergency alarms from SCADA

2.2

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

2.3

Identify 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 send out work crews to identify faulty equipment.

3

Manage and develop responses to consumer enquiries on outages

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

Outline actions required for problem resolution based on work roles and responsibilities

3.3

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

3.4

Apply the following to assist with interpretation and reaction to reports:

(a) drawings and documents

(b) past events

(c) weather conditions, and

(d) other factors

4

Plan and coordinate system outages required for network operation and maintenance

4.1

Compare the approaches of planned vs. unplanned maintenance

4.2

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

4.3

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

4.4

Explain fundamental considerations for:

(a) deploying work crews, and;

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

4.5

Analyse reports from work crews after inspection and maintenance, with reference to:

(a) updating of records, and;

(b) initiation of follow-up measures.

5

Analyse and apply communication techniques for network monitoring and control

5.1

Outline effective communication methods for network monitoring and control

5.2

Compare the application of each of the following for network monitoring and control:

(a) TMR

(b) microwave

(c) power line carrier

(d) UHF handheld equipment

5.3

Explain the need for voice communication protocols

5.4

Explain barriers for effective communication and propose different techniques for establishing clear and intelligible communication

ASSESSMENT STRATEGY

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

CONDITIONS OF ASSESSMENT

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisations (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

Assessment Conditions:

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Assessments may be open book assessment and may be completed off campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.
