“…The level of reliability of the functioning of the energy system is determined, along with other factors, the reliability and operational characteristics of the used electric power equipment, control devices and systems, including the characteristics of microprocessor-based devices for automatic control, protection and automation [13]. At the same time, products offered on the electric power market are not always free from algorithmic and software errors, and adaptation to operating conditions in power systems is not performed properly [14].…”

For reliable operation of electrical systems, it is necessary to ensure the stability of parallel operation of power plants and power systems. Violation of their stability leads to the repayment of a large number of electricity consumers, equipment damage and other negative consequences. Excitation systems can improve the quality of voltage control during sudden fluctuations in the load and with a short circuit at the output of synchronous generators. The aim of this work is to verify the automatic excitation controllers installed during the modernization process on the generators of the Syrdarya TPP in the DISILENT power factory software package. The article presents the results of a study in which the effect of the installed system of automatic control of excitation in the process of modernization on the quality of transient indicators is analyzed. Transient analysis showed an improvement in transient quality indicators such as decay time, overregulation and static error.

“…Some literature discussions are on Voltage Regulation Distribution Transformer using On Load Tap Changer [29], Automatic Voltage Regulator (AVR) at generation side [30], and fuzzy logic based coordinated Power System Stabilizer (PSS), together with AVR at the generation side [31]. Others include synchronous Condensers (SC) with techno-economic analysis in [32,33], mechanically switched capacitors [34], and coordinated control between the switched capacitors and Static Synchronous Compensator (STATCOM) to avoid square voltage fluctuations [35].…”

Aggregation Strategy for Reactive Power Compensation Techniques—Validation

2019

Reactive power provision is a vital ancillary service, which provides opportunities to service market and power generators. The net reactive power in a balanced power grid needs to be zero, and the imbalance occurs due to the capacitive and inductive behavior of the extensive transmission lines, and because of the intermittent behavior of load-demand. This mismanagement in reactive power causes voltage instability, and hence the paper compares the most common reactive power compensation techniques, which are prevalent in both literature and commercial levels. The paper perceives the trade-off between the compared techniques, and realizes to use the aggregation of different techniques to present a coordinated control mechanism that complies with the Italian regulations. The parameters for the proposed aggregation include the amount of reactive power, real power losses during reactive power provision, and response time. The paper then implements IEEE 9 bus transmission-generation system in DIgSILENT to set up the platform for validation of the proposed strategy. Finally, it simulates Transmission System Operator (TSO) test cases on the implemented test system.
