3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Virtual synchronous machine virtual synchronous machine; VSM By simulating the electromechanical transient characteristics such as the inertia and internal potential of the synchronous machine, the power and voltage operating external characteristics of the port are similar to the synchronous machine Power electronic converter system or equipment. 3.2 Virtualsynchronousgenerator The port characteristics appear as a virtual synchronous machine for generators to generate electricity. 3.3 Virtual synchronous motor The port characteristics appear as a virtual synchronous machine for load power consumption. 3.4 Activepower-frequencyregulationcoefficientofVSM The rate of change of the active power of the virtual synchronous machine with frequency. Note. The active frequency modulation coefficient of the virtual synchronous machine is usually expressed by Kf, and the calculation method is shown in formula (1). Use the virtual synchronous machine's active power change to mark the unit value (in the virtual The ratio of the rated active power of the pseudo-synchronous machine as the reference value) and the per-unit value of the system frequency change (take the system rated frequency as the reference value) is expressed. ......
