The present application relates to the technical field of power supplies, and discloses a method and an apparatus for configuring distributed compensators based on voltage stiffness indexes, and a computer device, a computer-readable storage medium and a computer program product. The method is applied to a new energy power station comprising multiple input branches, and comprises: determining a value of a target voltage stiffness for each of the multiple input branches, wherein the voltage stiffness is used to represent a voltage support degree; determining a target capacity and a target number of distributed compensators arranged in each of the multiple input branches based on the value of target voltage stiffness, and acquiring a station capacity and a station number according to the sum of target capacities and target numbers of the multiple input branches; and configuring the distributed compensators for the new energy power station based on the station capacity and the station number, so as to configure the distributed compensators according to a target voltage support degree. The present application solves the problem that it is difficult to accurately evaluate actual support effectiveness of distributed compensators and acquire a configuration number and a configuration capacity of distributed compensators that match with actual requirements because the configuration techniques and indexes for distributed compensators in the prior art lack phase angle information of the relevant equipment.

The present invention relates to the technical field of offshore wind power equipments and discloses a jacket platform and an offshore wind power structure. The jacket platform of the present invention comprises a frame body and a damping and vibration-reducing device; wherein the damping and vibration-reducing device comprises a shell, a damper, a displacement amplification assembly and a connection assembly; the shell is hinged on a top of the frame body; the damper and the displacement amplification assembly are arranged in the shell, and the damper is connected with a power output end of the displacement amplification assembly; the connection assembly comprises a plurality of connection cables; one end of each connection cable is connected with a power input end of the displacement amplification assembly, and the other end of each connection cable extends out of the shell and is connected to the frame body, and every two adjacent connection cables are arranged to have an included angle therebetween. The damping and vibration-reducing device in this jacket platform can realize displacement amplification, enabling the damper to give full play to its vibration-reducing effect, and moreover, it can achieve vibration reduction in multiple directions, thus having a good vibration-reducing effect and being suitable for use in the complex sea-current load environment of the ocean.

Slotted element (1) adapted to co-act with a current collector of an electrically propellable road vehicle for supplying electric power to said vehicle. The slotted element is adapted to extend along a road section at least partly recessed in a road surface. The slotted element comprises an elongated body part (1') with substantially vertical conductor slot(s) (6a-b) extending in the longitudinal direction of the slotted element. Electric conductor(s) (5a-b) is/are arranged in a respective conductor slot.
