WSOS Features and Tools

An Overview

Introduction

WSOS is a software package developed by Nu-Lec Industries to support their range of automatic circuit reclosers and sectionalisers with intelligent electronic controllers.

More recently WSOS has developed its own features for which the controllers must provide software support.

FeaturesThis presentation provides an introduction to the following WSOS software functions:

User Defined Curves

Automatic Data Retrieval

Batch Change

Configurable IOEX

Configurable DNP3

Change of State Monitoring System

User Defined Curves

This feature is two tools in one:

Curve Viewer

Curve Editor

The Curve Viewer allows WSOS users to view standard and modified curves.

The Curve Editor allows standard curves to be edited or new curves to be created graphically.

This feature requires WSOS 4.14+

Curve Viewer Overview

The Curve Viewer is designed to show graphically how a protection curve’s shape is affected when curve modifiers are applied.

Phase and Earth protection settings can be modified in WSOS and the changes viewed straight away.

Other curves can be displayed on the same graph to allow comparisons with settings for other trips on the same or other reclosers.

Viewing Curves

To view a protection curve it is first necessary to select a protection group and a trip number/type from within WSOS to display the Trip 1, 2, 3, 4, Single Shot or Work Tag Settings screen

From here the Curve Viewer can be launched by clicking the “View Curve” button.

Curve Viewer

When launched the Curve Viewer displays the selected Trip number’s curve with all modifier settings applied.

User Defined Curve Editor Overview

The curve editor is a Microsoft Excel based application launched from within WSOS.

It is used to edit user defined protection curves by typing values into a table or by dragging individual points on the graph itself.

Built-in functions allow the curve to be manipulated around a selected point on the curve.

Range functions allow the curve to be modified across a number of points.

Creating New Curves

The easiest way to create a new curve is to:

load a comparison curve,

match the User Defined Curve to it,

Hide the Comparison Curve,

make edits to the User Defined Curve,

save the curve under a new name.

Select – Match – Hide Comparison

Save Curve As

Select User Defined Curves

Curve Selection attaches user defined curves to WSOS switchgear files which can then be written to switchgear controllers.



Uploading history files such as the Event Log and Maximum Demand records from remote switchgear is a costly time consuming exercise.

Automatic Data Retrieval was developed to automate this process.

Automatic Data Retrieval - Overview

Automatic Data Retrieval allows selected history files to be automatically uploaded from selected switchgear during pre-determined time periods on a regular basis.

The current status of the upload procedure for each switchgear can be displayed by WSOS.

If WSOS can communicate with the switchgear this feature can be used.

A level 50 WSOS licence is required for ADR.

Automatic Data Retrieval Screens

There are three ADR screens that are launched from the Customise menu.

Option Configuration– Select which data you want

uploaded from each device. Switchgear Selection

– Select when and how often to upload from each device.

Switchgear Status– A summary on the status of the

Automatic Data Retrieval for each device.

Batch Change

Batch Change

The WSOS Batch Change feature allows remote users to make changes to critical settings in a group of automatic circuit reclosers and/or load break switches where these changes are deemed necessary due to expected events such as bushfires or storms.

The required setting changes for each switchgear device can be configured in advance at the remote WSOS computer and the changes for all devices executed with a single command or at a predetermined time.

Input/Output Expander Module (IOEX Module)

Input/Output Expander Module (IOEX Module)

The Input Output Expander (IOEX) card enables easy interfacing of additional external equipment to Nu-Lec’s Pole Top Control Cubicle (PTCC).

This module allows the power utility to connect items such as external protection relays or an RTU as required.

The IOEX has:

12 optically isolated inputs and

8 voltage free output contacts.

IOEX Standard Map Inputs and Outputs

Standard Mapping has 8 used inputs and 4 spare

Some inputs have logic conditions applied

Standard Mapping uses all 8 available outputs.

Output 8 operates according to applied logic.

IOEX Standard Map Inputs and Outputs

Up to 8 outputs can be configured.

Each output can be configured to operate for a given status.

Outputs

Output 1 Switchgear Tripped

Output 4 Lockout

Output 8 Maintenance Required

Configurable IOEX

Custom maps can now be created for an IOEX card and loaded into a CAPM directly from WSOS.

The types of actions that can be mapped to each input or output is dependent on the software version loaded in the CAPM.

When the tool is started the user is asked to input the software version.

This is then used to retrieve a valid set of points to use when constructing logic within the tool.

Custom Mapping

Configurable IOEX Scope

The Configurable IOEX tool allows WSOS users to generate custom I/O mappings for an Input Output Expander Card (IOEX).

Logic can be applied to each point with up to five sets of logic or “actions” for each input and one trigger action for each output.

The Configurable IOEX Tool can only create mappings that are compatible with CAPM software versions 027-07.xx (CAPM 4) and 527-07.xx (CAPM 5) or higher.

The Tool can be used to read mappings from previous versions of software but can only create files for use with the newer software versions.

Distributed Network Protocol (DNP3)

Distributed Network Protocol (DNP3)

DNP3 is a communications protocol commonly used in the Electricity Supply Industry for the control and monitoring of switchgear devices.

The Nu-Lec DNP3 implementation allows users to interface their controllers to a SCADA system with a DNP3 master station.

The implementation includes a standard map of points for this purpose. Binary Input Points Analogue Input Points Counter Points Binary Output Points Analogue Output Points

Standard ACR Map

Configurable DNP3

Custom DNP3 maps can now be created and loaded into a controller directly from WSOS.

The mappings and I/O logic are created using the tool and saved to a DNP3 mapping file on the WSOS computer.

Once a valid file has been created, it is linked to the switchgear device configuration in WSOS and written into the controller.

The types of actions that can be mapped are dependent on the software version loaded in the Switchgear Devices controller.

When the tool is started the user is asked to input the software version.

This is then used to retrieve a valid set of points to use when constructing mappings within the tool.

Configurable DNP3 Scope

The Configurable DNP3 tool allows WSOS users to generate custom DNP3 I/O mappings and load them into a switchgear controller.

The Configurable DNP3 Tool can only create mappings that are compatible with CAPM software versions 028-01.xx (CAPM4) and 528-01.xx (CAPM5) or higher.

The Tool is available with WSOS 4.20 or later and will work on Microsoft Windows 98, NT4, 2000 and XP.



The Switchgear Monitoring System is used to setup and operate a Change Of State reporting system for Nu-Lec switchgear using modems and radios.

This tool allows the user to configure switchgear devices out in the field to automatically dial in and report abnormal conditions.

Network operators can respond to reported events locally or be contacted automatically if they are not in the office.

Automatic notification options include e-mail, recorded messages over a phone system or through a pager.

The monitoring system requires a level 60 WSOS licence

Switchgear being monitored must be capable of WSOS communications with the PC

Communications could be via radios, landlines, GSM phones etc.

In Call-Out mode, operators can be notified by SMS or pager.

On call operators can also receive a voice message via phone

Automatic E-mails can notify engineers of any alarms that have been generated

WSOS Configuration

Monitoring System Configuration

Each device to be monitored by the system needs to be configured so the Monitoring System knows how to respond whenever a defined event occurs.

Action Profiles

Action Profiles are used to define what action the Monitoring System will take when an event is reported by the switchgear device.

The action can be E-Mail, Dial Out (phone), SMS/Pager message, A combination of the above

This action will occur after a set time period has passed without the condition being acknowledged locally at the WSOS PC itself.

Monitoring System - Summary

The monitoring system can be used in two ways – locally or callout.

When used locally an operator is at the WSOS computer and responds to abnormal conditions using WSOS.

If the callout mode is being used the WSOS computer is left unattended and the system reports abnormal conditions by sending e-mail, SMS messages, Pager messages or recorded messages over a phone.
