// Given data
f = 50.0        // Frequency(Hz)
G = 100.0       // Rating of generator(MVA)
H = 5.0         // Inertia constant(MJ/MVA)
P_a = 20.0      // Acceleration power(MVA)

// Calculations
GH = G*H                // Energy stored in rotor at synchronous speed(MJ)
M = GH/(180*f)          // Angular momentum
acceleration = P_a/M    // Acceleration(°/sec^2)
