In order to obtain the transient power system measurement information, Wide Area Monitoring Systems (WAMS) should be able to collect Phasor Measurement Unit (PMU) data in a timely manner. Therefore along with the continual deployment of PMUs in Great Britain (GB) transmission system substations, a high performance communications infrastructure is becoming essential with regard to the establishment...
This paper presents and compares the results of two different approaches to identify the mode shapes and frequencies of the inter-area oscillations in the electrical power system of Great Britain (GB). The approaches are simulation-based analysis, carried out using the full dynamic model of the GB network in DIgSILENT PowerFactory, and measurement-based analysis, with data provided by phasor measurement...
Operation of power systems has become more complicated and therefore encounters more challenges. In this regard, Wide Area Monitoring System (WAMS) as a state-of-the-art technology provides an effective method for large scale power grid monitoring, protection and control. Phasor Measurement Units (PMUs) measure power system parameters including frequency, voltage and current phasors with high accuracy...
The inclusion of Phasor Measurement Units (PMUs) to the electricity network of Great Britain is providing insight beyond the steady state, into the behaviour of the power system. Synchronised measurements, from a fair geographical distribution of devices are allowing the regional differences, following transient events, to be examined. This is forcing revision of the previous assumption of network-wide...
The inherent reduction in inertial frequency response resulting from a shift in generation mix towards renewables, is presenting a range of operational planning challenges for transmission system operators (TSOs) globally. Dictating the ability to maintain frequency following significant mismatches in supply and demand, it is of great consequence to the real-time operation of the power system. In...
The Phasor Measurement Unit (PMU), with its ability to directly calculate the power systems state variable, is deemed vital to achieving the wide area monitoring and control requirements of the Smart Grid. Making effective use of the data however, is not without its challenges and the successful deployment of such a synchrophasor-based system requires enhanced testing and validation. The development...
National Grid, the Transmission System Operator for Great Britain, has recently installed a Wide Area Monitoring System (WAMS), to improve the real-time view of the power system. Phasor Measurement Units (PMUs) have been installed, primarily through upgrades to digital fault recorders, as an extension to dynamic system monitoring. This paper reviews the development of WAMS on the GB System and presents...
