“…This three terminal radial system will be protected in a non-selective manner with AC-side circuit breakers. To enable effective commissioning and operational training, converter control and protection (C&P) replicas (with a simulated electrical system) for the three terminal system are present at The National HVDC Centre [13].…”

This paper outlines the demonstration of partially selective and fully selective HVDC protection systems using a simulated industrial case study HVDC network, hardware HVDC protection IED prototypes, and simulated HVDC circuit breaker models. A summary of results are presented demonstrating the performance if the protection IEDs and indicating successful operation of the overall HVDC protection system according to system-level indicators. The presented results are intended to increase confidence that HVDC protection systems for multivendor HVDC networks are near ready for full-scale industrial implementation.

“…A more recent trend is the CHIL testing of replicas of the control system of HVDC and FACTS devices by utilities, mainly TSOs. The complexity and increasing importance of HVDC and FACTS in contemporary power systems, the difficulty of maintaining simulation models (e.g., black box models provided by the manufacturer)-leading to differences between the modeled controllers and the actual controllers in the field-and the need to test control changes in a safe environment before field implementation are key drivers for this development [102,103,109]. Certain utilities operate a DRTS, and obtain from the HVDC or FACTS manufacturer a replica of the control/protection system, which is an exact copy of the actual control/protection system installed on site [110].…”

“…Moreover, interactions between several HVDC systems and FACTS devices can be studied (e.g., provided by multiple vendors), maintenance can be supported, future software updates can be validated, and the training of engineers can be facilitated [112]. As a major source of modeling uncertainty is removed, such platforms are considered to be a reliable tool for longer term studies [109,111].…”

FACTS Providing Grid Services: Applications and Testing

et al. 2019

The role of flexible alternating current transmission systems (FACTSs) in the provision of grid services is becoming increasingly important, due to the massive integration of intermittent renewable energy sources, energy storage systems, and the decommissioning of thermal plants. A comprehensive literature review of grid services offered by FACTS is performed, focusing on the different grid services that they can provide, such as power flow control, reactive power control, voltage control, power quality improvement, harmonic mitigation, improvement of transient stability, and damping of inter-area and intra-area oscillations. These grid services need to be realistically and economically validated in suitable testing environments. A review of relevant standards, guides, and the literature is performed, which covers the entire range from functional specification and factory testing up to the field testing of FACTS. Advanced industry practices, such as controller hardware in the loop (CHIL) testing of FACTS controllers by the manufacturer, and recent trends, such as CHIL testing of replica controllers by the owner, are underlined. Limitations of conventional testing and CHIL testing are explained and the use of power hardware in the loop (PHIL) simulation for FACTS testing is discussed. CHIL and scaled-down PHIL tests on a transmission static synchronous compensator (STATCOM) are performed and a comparison of the results is presented.

“…However, complicated control and protection systems like HVDC and FACTS should be investigated regularly for continuous analysis of site issues, even after the Site Acceptance Test (SAT). China, France, Canada, and England have established and operated HVDC replica controllers, which have fully replicated the actual on-site controller since early 2010 [15][16][17][18]. China has installed all of CSG's HVDC replica controller for study, validation, and maintenance.…”

The purpose of this paper is to introduce, examine, and evaluate the industrial experiences and effectiveness of a Thyristor Controlled Series Compensator (TCSC) replica controller installed in Korea in 2019 through a review of its configuration, test platform, and practical application, and further to propose operational guidelines for replica controllers. Four representative practical cases were conducted: a Dynamic Performance Test (DPT) under a sufficiently large-scale power system prior to the Site Acceptance Test (SAT), pre-verification for on-site controller modification during operation stage, parameter tuning to mitigate the control interaction, and time domain simulation for Sub-Synchronous Torsional Interaction (SSTI). None of these four cases can be performed in a Factory Acceptance Test (FAT) or on-site. Therefore, TCSC control performance was accurately verified under the entire Korean power system based on a large-scale real-time simulator, which demonstrated its effectiveness as a powerful tool for operations including multiple power electronics devices. Our review herein of these four practical cases is expected to show the usefulness of replica controllers, to demonstrate their strength to deal with practical field events, and to contribute to the further expansion of the application area from a perspective of electric utility.
