If the dive protocol is unsuccessful and the rated speed depth is not achievable (Step 706), the THOR controller may cause the hydrokinetic device to enter the idle protocol (Step 709) at a predetermined depth and may include further execution of the ADCP query protocol (not shown). In this regard, the variable weight effector, the variable lift effector, the variable drag effector, and/or an energy transducer change effector, which may include a rotor blade pitch angle change effector, may be controlled by a station (not shown), such as, for example, a THOR HQ controller, located in/on the water (for example, a stationary platform, a vessel, or the like), in/on land (for example, a building structure, a vehicle, or the like), or in the air (for example, an aircraft, a satellite, or the like). Further, an energy transducer may be a variable pitch control rotor hub or another energy conversion device capable of converting the kinetic energy of the moving fluid into useable electrical power that may also have a means to engage to and disengage from the fluid flow.
The energy transducer change effector may include, for example, a downstream horizontal axis variable pitch control rotor hub 108 that is coupled to the onboard electrical generator (not shown) to effectuate rotor blade pitch angle changes to a plurality of rotor blades 107 to cause the rotor 109 to be engaged with the current flow in an operational condition (for example, as seen in FIG. The variable effector may comprise: a variable weight effector that is configured to adjust a weight of the hydrokinetic device; a variable lift effector that is configured to adjust lift of the hydrokinetic device; a variable drag effector that is configured to adjust drag of the hydrokinetic device; or an energy transducer change effector that is configured to adjust a rate at which the kinetic energy is harnessed by the energy transducer. The device comprises: an energy transducer that is configured to harness the kinetic energy; an electrical generator that is coupled to the energy transducer; a variable effector that is configured to effect at least one of a weight, a lift or a drag of the device; a power output sensor that is configured to detect an actual generator power output level of the electrical generator; and an onboard controller that is adapted to control the variable effector to change at least one of the weight, the lift, or the drag of the device to adjust an operating depth of the device based on a difference of the actual generator power output level and a target generator power output level.

According to a still further aspect of the disclosure, a method is provided for controlling a hydrokinetic device that includes an energy transducer. The disclosed device appears to employ a constant depth, variable speed method analogous to that disclosed in U.S. 6 to cause more rapid convergence of the actual aggregate power output level and the target aggregate power output level without departing from the scope or spirit of the disclosure. The plurality of parameters may comprise: a free stream current speed in a column of water; an actual depth of the hydrokinetic device in the column of water; a mooring cable tension of a mooring cable; a presence of a marine creature that may create a collision hazard; a passage of a potentially catasrophic weather event; an actual generator power output level; or a power modulation factor. The predetermined condition may comprise: an aggregate vertical force balance that is substantially zero; an aggregate drag force balance that is substantially zero; or a depth that corresponds to a free stream current speed.

The power control process 800 may be executed by the THOR controller a vast majority of the time, causing the hydrokinetic device to track and recapture the rated power depth when the assigned power modulation factor is substantially equal to unity, or track and recapture the specified partial power depth corresponding to a power modulation factor that is less than about unity. The THOR controller may further monitor a communication link for a command from the THOR HQ, or the THOR controller may generate its own command (Step 705). If a dive command is determined to have been received (YES at Step 705), then the THOR controller may execute the dive protocol (Step 706), which may successfully conclude with the hydrokinetic device descending to the rated speed depth. The hydrokinetic device 100 may be retained in the water by a mooring system, such as, for example, the mooring system described in co-pending U.S.

Each THOR Controller may initiate a general individual control process 700 (for example, shown in FIG. The THOR HQ may specify the target aggregate power output level for the entire farm array of hydrokinetic devices, or a subset thereof, such as, for example one or more individual hydrokinetic devices. As seen, as the free stream current speeds increase, the power output by the device increases with the cube of the speed until the rated power is reached at point “1”, which occurs at the rated speed. As the free stream current speeds increase, the drowning force increases, thereby pulling the hydrokinetic device downward until the vertical forces again balance at the deeper depth. To move from the state C to the state B, a rotor (energy transducer) disengage transition process (or protocol) 1200 (shown in FIG. Further, anytime the energy transducer is engaged with the flow, for example rotor 109 is in the engaged position with the rotor blades pitched to the operational condition with hub 108 rotation in motion, the drag flaps 112 may be fully retracted in a low drag or no drag condition; and, anytime the energy transducer is disengaged with the flow, for example rotor 109 is in the non-operational disengaged position with the rotor blades pitched to a fully feathered condition and hub 108 rotation may be halted, the drag flaps 112 may be partially deployed for less than high drag condition, or fully deployed for a high drag condition.
