General Operations
State Estimation and Topology Error Identification
Load Management and Emergency Control
Fault Location
General Operations


The testing of PMACS is to ensure the capability of
PMACS in failover, alarm handling, communications,
and availability
Switching between main and backup systems
–
–

Switching between primary and back up computer system
Switching between primary Master station and secondary
Master station
Alarms and alert messages
–
–
–
Multiple number of system constraint violations
Current constraint violations at multiple locations
Voltage constraint violation at multiple nodes
General Operations

Availability Test
–

A = uptime/(uptime + downtime)
Communications Test
–
–
–
Data transfer between the science nodes and the
Master stations
Data consistency between primary and secondary
Master stations
Communications and data transfer between the
Master stations
State Estimation

The testing of State Estimation algorithm in
handling missing data and error of system
data
–
–
–
–
Failure of all measurements at a single science
node
Failure of a string of measurements
Failure of multiple measurements not in a string
Error in the assumed value of the link resistance
Topology Error Identification

Evaluation of the topology processor for
different topologies and load configurations
–
–
–
Low system loads
High system loads
Regions of simultaneously high and low system
loads
Load Management and Emergency
Control



To verify proper operation of the software,
communications and load shedding functions
are tested
Check interface with the science node
instruments
Check interface with Data Management and
Archiving System (DMAS)
Load Management and Emergency
Control

Load shedding to prevent voltage collapse
–

Load shedding to reduce backbone line currents
–

Monitor voltage profile at individual nodes to prevent under
voltage at science nodes
Estimating backbone current based on results of State
Estimation to prevent over current
Load is shed according to the schedule of power
selected by the end users in accordance with the
user contract.
Fault Location

Divide system into 3 areas and perform test
cases within each
–
Radial branches connected directly from the
shore station

–
Network area with T connections

–
Fault current from each end of the link equal to the
current outputs at the shore stations
Fault current from neither end of the link is known.
Radial branches coming out of the network

Fault current is the sum of shore stations output currents
Fault Location

The following abnormal conditions will be
tested
–
–
–
–
Multiple measurements not available at one or
both shore stations;
Voltage and current measurements are only
available at one shore station;
Significant error associated with cable
resistances;
Significant error associated with voltage drops
