What is disclosed is a vertical-axis wind turbine that looks somewhat similar to a vertical pole during no-wind or relatively low-wind conditions, i.e., when the turbine is waiting for relatively windy conditions, and that transitions between its “waiting state” and “wind harnessing state” automatically. Yet, to automatically transition between states, the turbine uses relatively few moving mechanical assemblies and uses no electric parts. The turbine has levers attached radially to a vertical mast and one or more wings attached to each lever. Each wing's mounting angle causes the wing to move the lever to which it is attached to deploy the wing(s) attached to that lever to rotate the mast. At an approximate rotation point of the mast, to avoid the deployed wing(s) from unduly opposing the mast's rotation, the wing's angle facilitates the retraction of the wing(s). The net drag of the wing(s) serves to rotate the mast.

Provided are a method and a terminal for configuring reactive power capacity of a power grid to which offshore wind power is connected on a large scale. Static voltage stability indices of substations in a regional power grid to which the offshore wind power is connected on the large scale and at multiple points and relative dynamic voltage drop area indices for an N-2 fault are calculated. Thus, weak nodes in voltage stability are located, thereby implementing a prediction of a risk to the voltage stability of the regional power grid. These nodes are used as candidate reactive power compensation configuration nodes. An objective function is established as the minimum total cost of reactive power compensation devices at the candidate reactive power compensation configuration nodes. A multi-type reactive power optimization configuration model including static voltage stability constraints, voltage stability constraints in a faulty state, and other constraints is solved. Thus, a configured static reactive power compensation meets a voltage regulation demand during normal operation of the power grid, and a configured dynamic reactive power compensation meets a demand for reactive power support in the event of a severe fault in an important transmission channel. In addition, the total cost of a reactive power compensation configuration is minimized so that a stable voltage and an economical reactive power configuration of a system with a high proportion of offshore wind power are
