Abstract

The invention provides a method for evaluating the generating capacity of an MGP system. The method comprises the steps of starting an MGP system experiment device, wherein the MGP system experiment device comprises a driving power supply group, a motor, a generator, a rotating speed measuring instrument and a load group, the driving power supply group is connected with a power supply terminal ofthe motor, an output shaft of the motor is in shaft connection with an input shaft of the generator, the load group is connected with a load terminal of the generator, and the rotating speed measuringinstrument is located between the motor and the generator and is connected with the motor and the generator respectively; adjusting an access load of the load group; measuring the output rotating speed of the motor corresponding to the access load; measuring the output voltage of the generator corresponding to the access load; and evaluating whether the generating capacity of the MGP system meetsthe requirements or not.

Description

technical field [0001] The invention belongs to the technical field of MGP systems, and in particular relates to a method for evaluating power generation of an MGP system. Background technique [0002] Synchronous motor-generator pair (MGP), referred to as motor pair, MGP system consists of a synchronous motor and a synchronous generator, the two are connected coaxially, and the electric energy generated by the new energy is converged to drive synchronous The motor rotates, and the synchronous motor acts as the prime mover to drive the synchronous generator to generate electricity and connect to the grid. [0003] In the prior art, CN207198918U discloses a power generation evaluation system of a household photovoltaic power station, which collects power generation environment data in real time and combines released meteorological data with historical data to predict and evaluate power generation, and predict and analyze future power generation conditions. [0004] The prior...
