HYDROELECTRIC POWER STATION CONTROL SYSTEMS
IFAC Proceedings Volumes, 1986Summary EDF runs 460 unattended hydroelectric power stations. The many years of experience acquired has enabled EDF to write formal guidelines on automation, which are all the more necessary because hydroplant is increasingly used for load following and power system control.

Direct Control of Power System Dynamics
2021One of the main causes of power system instability is low-damped inter-area oscillations. It is important to damp out low-frequency oscillations effectively and to provide necessary precautions in order to avoid major separations of power systems and cascading blackouts.

Adaptive control in power electronic systems
2021Power electronics systems are subject to uncertain and time-variant parameters and also disturbances e.g. due to aging, thermal effects, load changes etc. Therefore a fixed and linear control structure may not be able to present and give the desired performance under all conditions.

Interactive Relay Controlled Power System Modeling
IEEE Power Engineering Review, 1991Four fundamental algorithms that make it possible to simulate numerous types of protective relay systems are identified. The characteristics of these fundamental modules necessary for building an embedded relay model within an EMTP (electromagnetic transient program) are discussed.

Integrated power/attitude control system /IPACS/
Mechanics and Control of Flight Conference, 1974An integrated power and attitude control system (IPACS) for spacecraft is described. The system utilizes energy wheels for electrical energy storage as well as attitude control. Results from the feasibility studies of this concept are summarized and indicate potential weight and cost savings up to 30% over conventional power and control systems. The IP

VPS - versatile power supply control system
14th IEEE-NPSS Real Time Conference, 2005., 2005Versatile power supply (VPS) control is a component of a network-based control system and SCADA software with a client/server architecture developed using the data logging server control by National Instruments. Installing OLE for process control (OPC) client in the data server of VPS allows access to every kind of CAEN power supply (SY1527, SY527, etc.

MEASUREMENT BASED CONTROL OF POWER SYSTEMS
IFAC Proceedings Volumes, 1986Publisher Summary This chapter provides an overview of measurement-based control of power systems. The measurements are generally of fundamental frequency components of the signals in the presence of extraneous components in the power system voltage and current signals.

Power System Stability Controls
2007Power system synchronous or angle instability phenomenon limits power transfer, especially where transmission distances are long. This is well recognized and many methods have been developed to improve stability and increase allowable power transfers.
