Station Level Solutions
Realizing the benefits of an advanced power system management requires the automation of local operations, and the collection, evaluation, and forwarding of data on the power system status and plant condition to higher-level systems. The SAS600 station level solutions provide remote control and monitoring functions for all kinds of substations from distribution level to extra-high-voltage substations.
Station Level Solutions provide a central database, HMI, and gateway functionality at the substation level. The substation communication networks are part of the solution. It inter-connects and integrates the bay level intelligent electronic devices (bay control and protection devices) using the well-proven IEC 61850 standard. They are easy to use and to adapt to customer-specific requirements.

Power transmission substations are very often unmanned and can be physically distributed over quite a large area. They usually not only contain the high voltage level but also the sub-transmission and distribution as well. It is essential to have a common substation automation system for all voltage level that can provide reliable remote connection for operational purposes and to have a fast and secure remote access to data for incident analysis.
Typical customer requirements
- Unmanned substations
- High reliability for remote control
- Rarely changes once in operation
- Comply with security regulations
- Significant number of IEDs
- One, two, three or even more voltage levels
- Single or double busbar plus transfer bus or one and a half breaker configuration
- Fast incident analysis required by maintenance team
- Integration of energy metering for control of power flow
- One system to cover all substation monitoring functions
Features
