Abstract
Systems and methods for monitoring power generation are provided. For example, such a system may include a gas turbine, an electrical generator coupled to the drive, a controller coupled to the gas turbine, and a compliance monitor. The gas turbine may generate a torque, and the electrical generator may provide power to a power grid based on the torque. The controller may cause the gas turbine to vary the torque in response to a frequency disturbance occurring on the power grid. The compliance monitor may determine whether the response to the frequency disturbance complies with a specification for the response.
Claims20
A system comprising:
- a gas turbine configured to generate a torque;
- an electrical generator coupled to the gas turbine, wherein the electrical generator is configured to provide power to a power grid based on the torque;
- a controller coupled to the gas turbine, wherein the controller is configured to cause the gas turbine to vary the torque as a response to a frequency disturbance occurring on the power grid;
- and
- a compliance monitor configured to determine whether the response to the frequency disturbance complies with a specification for the response.
A system comprising:
- an electrical generator compliance monitor configured to compare, when an electrical generator carries out a primary frequency response as a response to a frequency disturbance of a power grid, a contribution feedback and a contribution demand to determine whether the primary frequency response of the electrical generator complies with a specification for the response of the electrical generator.
A method comprising:
- initiating a primary frequency response of an electrical generator when a grid frequency disturbance occurs;
- determining a contribution demand of the electrical generator based at least in part on a droop response of the electrical generator and an amount of the frequency disturbance;
- measuring an output of the electrical generator to determine a contribution feedback;
- comparing the contribution feedback to the contribution demand;
- and
- indicating when the contribution feedback does not comply with a specification for a relationship between the contribution feedback and the contribution demand at a predetermined time.
