DIgSILENT StationWare provides a reliable central protection settings database and management system for the complete power system substation data, both to manage the various control parameters and to centrally store substation related information. StationWare is based on the latest .NET technology.

StationWare stores and records all settings in a central database, allows modelling of all relevant workflow sequences, provides quick access to relay manuals, interfaces with manufacturer-specific relay settings software, and integrates with PowerFactory software, allowing powerful and easy-to-use settings coordination studies.

Link to PowerFactory

PowerFactory's data exchange facility allows it to access the settings stored in StationWare, such that these may be used as input for the powerful PowerFactory system simulation and protection setting tools. Settings that are calculated by using these tools may then be transferred back to StationWare.

What is the idea behind StationWare?

Modern numerical relays have a large number of settings that are determined, stored and communicated by proprietary software solutions (these may even be suitable for only a particular manufacturer or even a series or type of relay). This results in a fragmented and distributed settings "database." DIgSILENT StationWare provides a single system that incorporates all such different device protocols, thereby providing one manageable software data storage system, based on modern IT techniques, facilitating data interfacing and exchange in a transparent and hassle free manner.

Data Management

DIgSILENT StationWare is an extended and extendable system with regard to the type of information stored in it. The device list managed by DIgSILENT StationWare has no limits; and may be extended according to the number of devices to be managed.

Structured display

The settings management database stores the settings and data associated with protective devices, such as relays, CT's, VT's and circuit breakers. In reality these devices are all assigned to switch bays, which in turn are situated in a substation. Substations are located in different areas, which belong to geographical regions. These various sub locations may be configured in exactly the same manner as your network is arranged. In addition, relays themselves may have several different settings groups, each consisting of sometimes hundreds of individual setting parameters, that may similarly be exactly configured and noted.

Target data in just a few clicks

Using a centralised data repository provided by StationWare the user may search settings records using certain criteria, thereby quickly and easily accessing the required data from the huge set of data that is stored for power electrical systems.

Navigation help window

The navigation window allows you to quickly move to any target data required, without needing to page through data levels.

Historic view mode

Historic data, which may be used to evaluate the network as it was at any particular point in time, may be recalled for analysis. Such analysis, together with knowledge of system experience, can lead to improved stability and availability, simultaneously and automatically increasing expert knowledge.

Audit trail available

With the audit trail rooted deeply inside this application all changes can be viewed. That means information about actions and notes won't be lost any longer.

Workflow Sequence

DIgSILENT StationWare supports the modelling of workflow sequences. Workflow sequences are generally defined by a state-graph consisting of states and state-transitions. Each settings record contains the "settings status" as a common property.

From the "settings status"-field the state of a specific relay settings record can be clearly identified. Using different colours to indicate the current status of a settings record enhances this even more. For example, 'Settings in Service' is shown in green, 'Settings calculation progress' in red, etc.

Management features

StationWare allows the settings status and its transitions to be linked to the user management. Some user groups have the right to modify relay settings at most phases in the workflow sequence, whilst other users may be only allowed to work at restricted levels. Field technicians for example will typically only be authorized to forward the status from "Settings applied" to "Settings applied and tested" or to "Rejected" should the settings not have worked for whatever reason.

Every single one of such state changes is stored with a date and time-stamp as well as the ID of the user who changed the status. The user may also add a description to a status change to record important information pertaining to the state change, which later on is displayed in Audit trail.

Role based security inside

Users are managed by role based security; for each administrative function there is a corresponding right which expands the levels between normal user-rights and unlimited super-user-rights.

For example there may be a user manager to administer the users and their rights. Another group who are the device managers create settings templates (called schemes), that other user groups (settings engineers / technicians) may use for modelling substations.
