.ThermoPower.Electrical.Generator .ThermoPower.Electrical.GeneratorThis model describes the conversion between mechanical power and electrical power in an ideal synchronous generator, with ideal voltage control. Only active power generation is considered.
For proper system initialization and operation, it is recommended to use the generator model to represent the overall inertia of the turbo-generator group, i.e., to connect the generator model to turbine models that do not have any inertia on their own.
The inertia of the turbo-generator group is characterized by the
acceleration time Ta, which is defined as two times
the ratio between the turbo-group kinetic energy at nominal
rotational speed and the nominal turbo-group power. Oftentimes, the
time constant H is given instead, which is defined as
just the ratio between the turbo-group kinetic energy at nominal
rotational speed and the nominal turbo-group power. Obviously,
Ta = 2*H. Typical values of Ta are
beteween 5 s and 15 s.
In order to obtain well-posed initialization problems, it is
also necessary to set referenceGenerator = true on one
(and only one) generator for each synchronously connected island at
the initial time. This ensures that all initial voltage angles are
well defined. Please note this is not required if the generator
belongs to a system connected to a Grid component, as the
grid provides a reference for the initial voltage angles.
