OVERVIEW
Power System Dynamics, PSDAC,
is a company that has been in the electric power industry since 1994 and has
developed unique and appropriate methods of solving the dynamics of electric
power systems. Due to their novelty and usefulness, those methods are creative
as well as innovative because they lead to practical results and server-based
computing products which allow you to centrally execute dynamics applications
and to display the results anywhere on your network in a secure manner. The
Power System Dynamics Server 01SDS is one of those products and it has been
designed to suit the ever-changing needs of electric utilities in managing
generation, transmission and energy. It has a Windows user interface and
supports a distributed set of relational databases across the typically
geographically spread system representing electric utilities.
01SDS FEATURES
01SDS uses a local area
network (LAN) adapter to access the data collected and locally and/or remotely
stored in the electric utility databases and generates dynamical behavior
studies, automatic generation control functions, production cost calculations,
economic and optimal power flow. The power system is made of nodes, each node
being allowed to have any kind of generation or load.
State-of-the art models are
used for:
· Prime Movers: hydraulic plant with single
tunnel/penstock or multiple penstocks and common tunnel and with or without
surge tank, fossil (Gas, Oil, Coal) fueled plant, nuclear reactor plant,
combustion turbine plant, combined cycle plant and Diesel turbine.
· Synchronous machines (generators, motors and
condensers)
· Asynchronous motors
· Excitation systems and power system
stabilizers
· Automatic generation control (AGC), frequency
and active power control including ACE and NERC's new control performance
standards
· Loads
· DC converter and DC control
· Control of reactive power and voltage (shunt
and series capacitances, static var system, shunt reactors, under-load
tap-changing transformers and subsynchronous resonance, FACTS)
· Transmission lines including Carson's
approximation and the approximation by Gary, Deri et al.
· Dynamic capacitances and corona
· Transformers
· Grounding
· Protection system including circuit breakers,
tripping equipments, detection elements and relays (overcurrent relays,
directional overcurrent relays, distance relays, power swing and out of step
relays, differential relays, bus differential relays, transformer differential
relays, reclosing relays)
· Disturbances and topology changes
· Time evolution including steady-states,
stability, bifurcation, collapse and chaos
· Optimization, energy management and decision
support including, in addition to AGC, the following functions: automatic
voltage (Q-V) control and voltage scheduling, dynamic security, energy pricing
and penalties with contract suppliers, fuel scheduling and fuel management for
thermal units, generation planning, hydro-thermal coordination, interchange
transaction scheduling, tie-line control and energy accounting, maintenance
scheduling, network planning, optimal power flow, production cost, pumped
storage, static state estimation, unit commitment, economic dispatch,
reliability, reserves (ready and spinning reserves), production simulation, economic
analysis methods, real-time pricing, electricity commodity trading, parameter
identification, load forecasting, energy management systems (EMS with RTUs,
SCADA and databases) and decision support.
SUPPORT FOR BOTH WINDOWS
AND NON-WINDOWS CLIENTS
01SDS can be accessed by all
Windows clients including Windows 3.x, Windows 9.x, Windows CE, Windows NT
workstations, Windows 2000 Workstations, Windows XP, Windows for Workgroups. It
also supports non Windows-based terminals such as DOS, web browsers and
Java-enabled devices (Netscape Navigator plug-ins, Microsoft internet explorer
ActiveX Controls, Java applets), OS/2 Warp, Apple Macintosh, Unix workstations
(HP-UX, Sun Solaris, SunOs, DEC, IBM AIX, SGI IRIX), a broad range of client
hardware including Pentium PCs, Windows-based terminals, network computers,
wireless devices, and information appliances, and even older and less powerful
hardware such as PCs with the Intel 286 processor and other legacy hardware. A
large screen or wall display (with detailed information viewed by zooming onto
the elements of the single-line diagram) is a client also able to access the
server and so are mobile workers such as field agents and crews. 01SDS is
virtually accessible by any client, and the access is at a near-LAN speed.

CONNECTIVITY TO 01SDS
01SDS is delivered to these
heterogeneous environments over corporate LAN, WAN links (T1, T3, 56kb, X.25),
standard telephone lines, broadband connections (ISDN, Frame Relay, ATM),
wireless connections and the internet using a third-party add-on (Citrix
Metaframe ä ). 01SDS can be connected to mainframes and
minicomputers; it can also be administered remotely to perform tasks such as
directory maintenance, virus scans, backups, reboots, etc... Furthermore, it
has a tight security system: the server owner has control over the users and
their access level which is determined from their profile (executive, operator,
field officer, company personnel, business partners,..). Users running the
application on the server and displaying the results through their keyboard,
mouse and display see only their individual session. Each session, including
application runs, data display is handled independently of any other session
and multiple simultaneous sessions from one or many clients are possible. 01SDS
supports popular LAN and WAN protocols, including TCP/IP, IPX/SPX, NetBIOS, and
direct asynchronous connections. 01SDS can also send faxes and e-mails. The
Interutility and Intercontrol Center Communications (ICCP, WSCC, ELCOM-90,
IDEC, BSC) can be incorporated.
CONNECTIVITY OF 01SDS TO
UTILITY DATABASES
After authorized access,
01SDS can read warehouse historical data from any local or remote database
server including Microsoft SQL Server, DB2, Oracle, Sybase, Informix,
Interbase, dBase, Paradox, ASCII as well as all ODBC compliant databases such
as Access, AS/400, Btreive, and many others.
