“…The R1 is the matched resistance of the cable. The measurement device includes an oscilloscope, a buffer amplifier and trigger circuit, a sensor, matched resistance, a cable, and measuring equipment, which together constitute the measurement system [20][21][22][23]. The signal obtained by the capacitance sensor is input to the measuring equipment via the cable for the collection and storage.…”

The recognition of transient overvoltage characteristics is the premise of disturbance compensation of the transient overvoltage. Based on that, the recognition algorithm of transient overvoltage characteristics based on symmetrical components estimation was proposed. The generation mechanism of the transient overvoltage in gas insulated switchgear (GIS) was analyzed. Then, the transient overvoltage was measured via the capacitive sensor method. The three-phase voltage of ultra-high voltage grid was asymmetrical when the transient overvoltage appeared. At present, the asymmetrical three-phase voltage was decomposed into the superposition of a symmetrical positive-sequence component, a negative-sequence component, and a zero-sequence component via the symmetrical components estimation to build the superposition model. The model was decomposed via the trigonometric identity and the modified neural network of the least mean square learning rule was used to estimate the parameter vector of the characteristic quantity of the transient overvoltage in real time. The feasibility of the proposed algorithm was verified via comparing the simulation of the proposed algorithm and the algorithm based on dp transformation. The experimental results show that the proposed algorithm has the advantages of a small operand, high detection precision, and fast action.

“…Super-twisting algorithm, called higher-order sliding mode of the second order, has been adopted to achieve maximum wind power tracking and reactive power regulation [14][15][16][17][18][19]. However, control gains for these schemes cannot be real-time adjusted along with variation of system uncertainty.…”

This paper proposes an adaptive gain second-order sliding mode control strategy to track optimal electromagnetic torque and regulate reactive power of doubly fed wind turbine system. Firstly, wind turbine aerodynamic characteristics and doubly fed induction generator (DFIG) modeling are presented. Then, electromagnetic torque error and reactive power error are chosen as sliding variables, and fixed gain super-twisting sliding mode control scheme is designed. Considering that uncertainty upper bound is unknown and is hard to be estimated in actual doubly fed wind turbine system, a gain scheduled law is proposed to compel control parameters variation according to uncertainty upper bound real-time. Adaptive gain second-order sliding mode rotor voltage control method is constructed in detail and finite time stability of doubly fed wind turbine control system is strictly proved. The superiority and robustness of the proposed control scheme are finally evaluated on a 1.5 MW DFIG wind turbine system.

“…Relative major (PI) and PI + reverberating (PI + R) controller-based plans were immediately proposed to adjust either to inconsistent or twisted system voltage circumstances [10,11]. The principal weaknesses nitty gritty for those plans are low-execution transient response, poor structure soundness, the necessity for isolating positive and negative progressions or/and symphonious sections of the framework voltage and besides of streams, in the particular occurrence of PI controllers, and nonappearance of power against parameter assortments [12].…”

“…Before long, the NS1-SMC beats those issues by superseding the sign limit with a smooth similar limit, for instance, the inundation or the sigmoid limits [18]. The NS1-SMC-based course of action in [19] is affirmed unmistakably with the reenactment results [20]. Diverse particular issues similarly as the profitability of high-control wind imperativeness systems are analyzed in [21].…”

Disregarding wind turbines has been conveyed an unmistakable fuel source and does not corrupt the air like other power assets, which relies upon consuming of petroleum products, for instance, coal or vaporous oil, since wind is a fluctuating wellspring of vitality it has experienced high request music and isn't fit to meet the base burden vitality request. Along these situation, this circumstance forces wind turbine generator system to have a power molding circuit called control converter that should be bore of changing the generator repeat and voltage to grid anyway existing converters are doing combating with low solicitation sounds just so when high request music occurs, there is a debasement in power quality and wind turbine needs single multi arrange converter. As to issue, this work showed a multi request symphonious remover subject to mixed multilayer influence converter which avoids high music bending to upgrade the influence idea of wind based influence plant by considering the going with attributes that prompts sounds, for instance, control adversity to adjust up to this expansion type rectifier is used, inadequacy current that is changed by imperfection current limiter and the high repeat part that is controlled using nonlinear inductor, at long last commotion is decreased by cascaded c type filter so this structure can battle with the high consonant mutilation and kept up the impact quality and the transient security of the wind turbine.
