DSA Manager


On-line Dynamic Security Assessment

 

DSA Manager provides an environment through which the security assessment modules in can be integrated into the real-time sequence of an energy management system (EMS) to provide on-line DSA capabilities.

Security Assessment OptionsScreenshot

DSA Manager can be configured to interface with any or all of the security assessment modules in DSATools™:

  • Voltage Security Assessment Tool (VSAT)
  • Transient Security Assessment Tool (TSAT)
  • Small Signal Analysis Tool (SSAT)

All supported analysis options in these modules can be applied; additional analysis options are also available in DSA Manager:

  • Base case security analysis
  • Security limit assessment (1-dimensional and 2-dimensional for voltage and transient security, 1-dimensional for small signal security)
  • Remedial measure analysis

Features

DSA Manager supports a client/server structure. Single or dual DSA clients can be configured (dual DSA clients to provide redundancy). Clients can be networked with an unlimited number of VSAT/TSAT/SSAT computation engines (servers) to form a distributed computation network, thereby meeting performance requirements for specific applications. In addition to assessing the real-time system conditions, DSA Manager can also be configured to perform DSA functions related to other analysis modes, such as forecast/prediction, market, study (some study functions can be done through ST DSA Manager), QA, testing, training, etc.

DSA Manager can also be installed on any Windows-based computer networked to the on-line DSA system to monitor DSA operation and to examine DSA results.

Various types of results are displayed in DSA Manager:

  • Security violation alarms
  • Security trend analysis
  • Security violation details and suggested remedial measures
  • Historical security results
  • Security limit nomograms
  • Custom time-domain, PV, and other plots

In addition, DSA Manager can save on-line DSA results in a data depository such as PI database and also in XML format for display on a third-party platform such as VOB.
