“…These data are recorded by measurement equipments; thereafter, they are injected to the model and its response is measured in order to tune the model parameters. This process, although misses the physical meaning of parameters, is simple and straightforward in practical applications [10]. In this method, some considerations must be kept in mind such as [1], [8].…”

This paper presents a rule-based approach using synchrophasor measurements for generating unit model validation and calibration. The proposed method utilizes frequency and three-phase voltage signals recorded by phasor measurement unit at the point of common coupling of unit transformers to the high voltage grid. In the simulation setup, by taking the hybrid data simulation technique in use, the signals are being injected to the subsystem of generating units through a voltage source, which models the truncated external grid. The measured and simulated active power oscillations are then compared to each other and the effects of generating unit parameters on the oscillation mismatches are extracted. The maximum amplitude and damping ratio of oscillations are two main aspects of the observed mismatches. To recognize the most effective parameters on these aspects, a sensitivity analysis technique is applied. Next, identified parameters are adjusted to calibrate the generating unit dynamic model. Finally, quantitative and qualitative perspectives of the proposed method are investigated through different sorts of actual disturbances. The obtained results demonstrate that the final calibrated model outperforms the existing one, and it can be used for power system planning and operation studies. Time domain simulations are performed by DIgSILENT power factory software.Index Terms-Model validation and calibration (MVC), phasor measurement unit (PMU), playback process, sensitivity analysis.

“…Efforts have been made using synchronized phasor measurement to validate dynamic models so that the simulation results can accurately reflect performance of the actual system [20][21] [23]. To ensure the model accuracy, the 2030 EI dynamic model is validated against synchronized phasor measurements by the frequency monitoring network FNET/Grideye, which is essentially a single-phase Phasor Measurement Unit (PMU) network at the distribution level [22] [23].…”

SUMMARYIn this paper, applications of phasor measurements to the Brazilian interconnected power system (BIPS) are presented. Two prototypes, the low voltage phasor measurement system (LVPMS), with phasor measurement units (PMUs) installed in nine universities throughout Brazil and the high voltage phasor measurement system (HVPMS), with PMUs installed in four substations in a transmission utility in Southern Brazil, are the first installations in the country. These experimental prototypes have been a rich source of experience on the use of syncronized phasor measurements. Line parameter estimation, detection of oscillation modes, disturbance analysis, and system wide model validation have been the main applications. The LVPMS measurements are acquired at outlet voltage while the HVPMS measurements are acquired at 525 kV substations. The monitoring and analysis of several events in the BIPS have shown that both systems can provide relevant and comparable information on the BIPS dynamics.
