“…In the tidal current turbine control systems, the I d component is used to regulate power factor or terminal voltage while the I q component is used to regulate the torque. This overcurrent problem can be generally protected by a so-called crowbar protection, which can be activated to short circuit the rotor windings during the fault and will be kept off until the stator voltage is recovered [36,37].…”

This paper analyses the effects of doubly fed induction generator (DFIG) tidal current turbines on a distribution grid under unbalanced voltage conditions of the grid. A dynamic model of an electrical power system under the unbalanced network is described in the paper, aiming to compare the system performance when connected with and without DFIG at the same location in a distribution grid. Extensive simulations of investigating the effect of DFIG tidal current turbine on stability of the distribution grid are performed, taking into account factors such as the power rating, the connection distance of the turbine and the grid voltage dip. The dynamic responses of the distribution system are examined, especially its ability to ride through fault events under unbalanced grid voltage conditions. The research has shown that DFIG tidal current turbines can provide a good damping performance and that modern DFIG tidal current power plants, equipped with power electronics and low-voltage ride-through capability, can stay connected to weak electrical grids even under the unbalanced voltage conditions, whilst not reducing system stability.

Abstract. In this paper, based on finite element method, Ansoft was adopted to study the static and dynamic characteristics of electromagnetic release. Firstly, electromagnetic release was split and made models. According to the actual material properties, the corresponding parameters were set. And after creating the mesh, calculation was processed. The results show how the electromagnetic force changes with the current and the performance of electromagnetic release in different short circuit current. OverviewElectromagnetic release of miniature circuit breaker is the core component of over current protection. It must meet the requirements of the tripping characteristic curve when the current is less than the specified value must not trip when the current value exceeds several times the rated current is required in accordance with the inverse-time tripping characteristic curve [1] . Due to the shorter trip time, the faster the circuit breaker cut short circuit. Therefore, the performance of electromagnetic release a greater impact on limiting miniature circuit breakers and breaking properties, Electromagnetic release of dynamic and static characteristics are very necessary [2] . This paper used Ansoft to calculate the electromagnetic force solenoid type electromagnetic release, and static and dynamic properties of electromagnetic release were analyzed.
