Konferensbidrag (refereegranskat)abstract
- This paper presents the implementation of an Open Source SCADA system in a laboratory and discusses methods for PMU data integration into SCADA. SCADA BR is a web-browser based SCADA that enables the user to access monitoring, control and automation equipment over multiple protocols. For implementation, protection relays from SEL are configured as DNP3 outstations to act as slaves and SCADA BR which is installed in one of the workstations in the laboratory acts as master. The evaluation of SCADA BR has been performed by executing a power system model in a real-time simulator and coupling its analog outputs with the protection relays. The integration of PMU measurements in the SCADA system and their use for monitoring is discussed. The limitations of the SCADA systems to fully utilize PMU data are also presented.

- This paper presents an overview of the software implementation of a real-time mode estimator application and its testing. The application was developed to estimate inter-area modes from both ambient and ring-down synchrophasor data from multiple phasor measurement units (PMU). The software application was implemented in LabVIEW using Statnett’s synchrophasor software development kit (S3DK), to receive real-time synchrophasor measurements. The different features of the application were tested using two types of experiments presented herein. The first experiment is performed using emulated signals from a simple linear model. The second experiment was designed to use a linearized representation of the KTH-Nordic32 power system model. These experiments are used to carry out quantitative analyses of the tool’s performance.

‘In Silico’ Testing of a Decentralized PMUData-Based Power Systems Mode Estimator

Konferensbidrag (refereegranskat)abstract
- This paper presents the software implementation ofa Phasor Measurement Unit (PMU) data-based mode estimationapplication in a decentralized mode estimation architecture. Thiswork builds from previous efforts in the development of a modeestimator implemented using a centralized architecture, meaninga set of modes were estimated for the whole system in a singleprocessing location. One drawback of mode estimators that usecentralized mode architecture is that the observability and thereforeestimation of important low-damped local electromechanicalmodes can be affected by the higher observability of otherdominant modes of the systems (e.g inter-area modes). This workproposes, implements and tests a decentralized architecture inorder to increase the observation capability to provide betterestimates of local low damped oscillations. In this architecture,the data from a single PMU or a group of local PMUs couldbe processed by a processor to estimate the modal parametersobserved at a specific part of the grid or observed by specificgroup of PMUs. The decentralized architecture and results oftests are presented in this paper together with comparison witha centralized architecture.

Modelica Classes of the Norwegian Grid for iTesla and SW-to-SW Validation
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Following the European network of transmission systemoperators for electricity (ENTSO-E) R&D Road Map,efforts of collaboration between the European transmissionsystem operators (TSO) have led to common researchprojects concerning power system operation suchas iTesla. iTesla aims to develop a common toolbox tosupport the future operation of pan-European power grid.This toolbox was developed to use Modelica models.The work presented here encompasses the developmentof Modelica classes for power gird componentsused by Nordic TSOs to model the Nordic synchronousgrid. The performance of these Modelica models havebeen validated through different test cases implementedin both Power System Simulator for Engineering (PSS/E) as domain-specific tool and a Modelica simulation environment.The results from dynamic simulations with thepresence of different perturbations have been compared tothe PSS/E reference to validate the Modelica implementation,reaching almost identical records between simulationresults from both tools.
