Introduction :

A PMU test generator is a calibration equipment that test PMU under different condition per IEEE C37.118.1.2011 and IEEE C37.118.1.2014 standards requirements by applying three phase signal with exact 120 degrees phase shift to the system and measure its response The response is to be compared with the generated signal.

Motivation :

In the global power system, the operation is often close to its stability limit, which means that any disturbance or fault may lead to power oscillation and cascade power outages. The motivation for this project is to use the PMU test generator for real-time monitoring to make power distribution more stable and secure and even to transition to renewable energy sources. Of course, under the leadership of Dr. Keith Kikkert, we will make a cheaper version of the model and reduce the cost of the model accordingly.

  • Phasor Measurement Unit (PMU) Testing System :

As Asia's first PMU test system, it can provide a complete IEEE C 37.118.1-2011 consistent dynamic and dynamic testing, which is the same as the original intention of our project, as well as the information given to us by our supervisor. This system ensures the safety and reliability of the smart grid to enhance the international competitiveness of PMU manufacturers [1].

  • 6135A/PMUCAL Phasor Measurement Unit Calibration System :

This system mainly introduces the real-time key task data of voltage, current, frequency and phase calibration in a distribution network based on PMU, which mainly used in today's smart grid. In order to ensure consistent, accurate and reliable PMU data, it is necessary to calibrate PMU correctly. This system is consistent with the motivation and principle of our project. The three-phase power calibration is also the standard requirement test for IEEE [2].The system is the only fully automated and traceable PMU calibration system currently available. It is also the perfect solution for third-party calibration rooms, power facilities, and organizations related to power transmission [2].The system consists of some hardware components, including the server PC side, which is the same as our project hardware needs to be controlled by the computer LabVIEW is a working concept [2].

Background

Phasor measurement Unit

PMU is a device used to estimate the amplitude and phase angle of phasor in power grid by using synchronous common time source. Nowadays, it is more used to detect whether the smart grid is stable. About the history of PMU, in 1893, Charles Proteus Steinmetz published a paper on clear mathematical descriptions of AC waveforms, which he called phasors, a small point of PMU for the first time. The phasor measurement unit (PMU), which was invented by Dr. Arun G. Phadke and Dr. James S. Thorp at Virginia Tech in 1988, was an early model of PMU, and Macrodyne built the first real PMU in 1992 [3]. Since the 1990s, PMU has been installed in power grids in North America and many other countries in the world. The field test of synchronous phasor measurement technology not only verifies the effectiveness of simultaneous phasor measurement but also accumulates experience for the field operation of PMU [3]. Synchronous phasor measurements will allow people to measure and analyze the state of the entire power system more accurately based on real-time data collected from phasor measurement units located throughout the network. Accurate and time-labeled phasor data can be collected promptly, which allows system controllers to quickly identify power system events, such as power flow problems, frequency variability from different parts of the system and dynamic angle separation problems, through visual systems. The monitoring provides an accurate method for controlling the power flow from multiple energy sources (nuclear, coal, wind). PMU provides utilities with more control and monitoring capabilities and is considered one of the most basic measurement devices in future power systems. PMU can reduce load and other load control technology, honestly realize the management of power system and improve the reliability of power grid by early detection of faults, to achieve the isolation of operating system, to prevent blackouts. Accurate analysis and automatic correction of system degradation source to improve power quality. These are the original intentions of this project [3].
