WebThe complex power injected by the generating source into the ith bus of a power system is given as: S i = P i + j Q i = V i I i * i = 1, 2, …, n … (6.56) where V i is the voltage at the i th bus with respect to ground and I i * is the complex conjugate of source current I i injected into the bus. ADVERTISEMENTS: WebPower Formula P = τ. ω Where, P is the power (work done per unit time) τ is the torque (rotational ability of a body) ω is the angular velocity (rate of change of angular displacement) . represent the dot product or scalar product The above equation can be rearranged to compute the torque required to achieve given angular velocity and power.
