Network source coordination performance test method and system thereof

Abstract

A network source coordination performance testing method and system, including an upper platform (1) composed of an embedded industrial computer and its peripherals, an intermediate platform (2) composed of a high-speed digital signal processor and its peripherals, a power amplifier and its The underlying platform composed of protection circuits (3). The upper platform uses a high-performance embedded industrial computer as a control microcomputer, and peripherals include a host (4) and a slave (5); communicate with the middle control board through a PCI interface, and perform wireless communication with the slave through a PCI interface. The intermediate platform takes the high-speed digital signal processor DSP56F807 as the core, and has multiple I / O ports and various peripheral devices. The bottom platform uses a high-power high-fidelity modular power device as a power output stage; the bottom platform is designed with a voltage power amplifier circuit and a current power amplifier circuit. The test method of the present invention can verify the coordination performance of the network source by taking advantage of the unit shutdown or maintenance opportunities, and can complete all tests within 15 minutes without the intervention of test personnel.

Description

technical field [0001] The invention relates to a network source coordination performance testing method and system, belonging to the technical field of power grid testing. Background technique [0002] Many large blackouts at home and abroad show that the coordination between the unit's network-related protection and limitation and the power grid is one of the key factors to ensure the safe and stable operation of the system. If the source network is not coordinated, it may induce accidents, and even cause serious consequences of accident expansion. [0003] In 2012, the State Grid Corporation of China carried out a special inspection of grid-connected units and network source coordination, and checked the grid-related parameters of 200MW and above thermal power units in a certain province. Through inspection, it was found that the rotor over-excitation limitation function of the excitation system of the generator set and the generator rotor overload protection, the low-ex...
