“…A survey of early application of a mechanically switched ShBR is reported in [12]. It is proposed to apply shunt resistors for braking hydro [13] or thermal [14] units. Current studies on ShBRs mostly focus on brake controller design [15], [16], and coordinated braking with fast valving [17].…”

Power system transient stability can be effectively improved by applying shunt braking resistors. This paper proposes multi-objective heuristics-based optimization for shunt braking resistor sizing. The proposed approach addresses three objectives: transient angle stability, transient voltage response, and mechanical stress of the turbine-generator shaft. The optimization problem was solved using a Python implementation of the multi-objective evolutionary NSGA-II algorithm. Based on the optimization model, comprehensive tests for multimachine IEEE 39-bus power system including single-and multi-objective simulations were performed. Pareto sets for various sets of objectives are obtained and discussed. The results show the complexity of the shunt braking resistor optimization process. Optimization studies were complemented by simulation tests performed for assessing of the impact of optimal shunt braking resistor on power system dynamic response. Detailed discussion of test results has confirmed the correctness of the proposed approach.

The paper illustrates the experience of application of the modern universal automation system for solving different problems constantly occurring in various areas of power industry. One of such universal automation systems has been applied in Russia both for investigation of Wide Area Measurement System features with reference to a lengthy interconnected power system and for analysis of irregular deviations of frequency in the power supply autonomous system with greatly variable load. In both cases, the identical SEL-421 devices produced in the USA have been applied as Phasor Measurement Units and as Digital Fault Recorders correspondingly. The comparison results of synchronized measurements in very lengthy interconnected power system and the simulation results of phase angles in the same power system are shown. The investigation outcomes of two utilization possibilities are illustrated: thyristor-controlled braking resistors, and PID regulation for decrease of frequency deviation in a power supply autonomous system with greatly variable load Index Terms-WAMS, PMU, measurement, simulation, power supply autonomous system, dynamic braking.
