2. What is the purpose of the VSCSAS system?

3. What is Felix F. Wu's main research interests?

4. What is the main purpose of the data acquisition flow chart?

Accepted Answer

This is the second part in a two-part paper on the development of a voltage stability constrained security assessment system ( VSC-SAS ).

Accepted Answer

In the VSCSAS system, a security subsystem, termed as user manager, is designed to manage and maintain the security of the whole system.

Accepted Answer

Her main research interests are power system dynamics theory, power markets, FACTS, power electronics, IT application in power systems etc.

Accepted Answer

A standard distributed system based on Database Management System (DBMS) [6] has three main software layers: DBMS, Applications and their Interfaces.

Accepted Answer

In such module, the following main functions can be available: (i) view account and password information; (ii) add new account; (iii) delete account; (iv) change account properties; (v) password protection control.

Accepted Answer

Once the power flow confirmation operation is finished, all the 24 case files (or more) are uploaded to the VSC-SAS main server and stored to another specified directory.

Accepted Answer

When the user finished the selection of the next day 24 case files (ormore) based on the GUI in the client/PC, the user can run PSS/E and VSAT software to edit and calculate these case files.

Accepted Answer

One is for the acquisition of real time case file(s) with the purpose of voltage stability analysis, in which the case file(s) will be downloaded to the VSAT server for the calculation of voltage stability, and another is for the acquisition of SCADA data including the voltage and branch circuit with the purpose of supervision, in which the corresponding real time data only are recorded to the database directly.

Accepted Answer

Once the user-defined special contingency file is formed, it will be uploaded to the on-line and off-line VSAT server, respectively.

Accepted Answer

Consider the possible use within actual or future Energy Management Systems, some interfaces including the real time data acquisition from EMS for the calculation and monitoring purposes, database management system and the generation of user-defined special contingencies etc. should be discussed in this section to follow.

Accepted Answer

In order to provide the more intuitionistic and dramatic result display, there are three types of chart to display different analysis results.
