Abstract

The invention discloses a primary frequency modulation test system and method for a new energy station. The system includes: an analog output source which is used for simulating the current and voltage output of a grid-connected point, and triggering a primary frequency modulation device to act; a message and recording integrated acquisition device which is used for acquiring a grid-connected point network message and fault recording; a simulation master station which is used for loading a primary frequency modulation online monitoring information model, wherein the simulation master station performs information interaction with the primary frequency modulation device through IEC104 or IEC61850 MMS, initiatively initiates remote control and remote regulation instructions, and records remote signaling and telemetering information in real time; a communication server which is used for loading a primary frequency modulation information point table, simulating a new energy station to perform information interaction with the primary frequency modulation device through IEC104, Modbus TCP or IEC61850 GOOSE, passively responding to an adjustment instruction initiated by the primary frequency modulation device and feeding back a target value; and a test interaction interface end which is used for calling the interface of the function module according to the test item of the primary frequency modulation device, returning test record data and automatically generating a test report. The system and method are used for laboratory detection and field test, the test means is flexible and convenient, and the test result is reliable.

Description

technical field [0001] The invention relates to a new energy station primary frequency modulation testing system and method, belonging to the technical field of electric power system automation. Background technique [0002] With the continuous expansion of the installed capacity of new energy and the continuous increase of incoming electricity from outside the region, the power system is facing structural difficulties such as the decrease of moment of inertia and difficulty in frequency control, and the security of the power system is facing serious threats. In order to prevent a sudden large power shortage in the power grid and cause a low-frequency load shedding action, causing a large-scale power outage, and to ensure the safe and stable operation of the power grid, a requirement for the deployment of a frequency regulation function for new energy stations is put forward. [0003] At present, the standards and regulations put forward requirements for the primary frequenc...

Problems solved by technology

[0003] At present, the standards and specifications put forward requirements for the primary frequency modulation function and performance of new energy stations, but there is no good test technical means for the current primary frequency modulation test

In the current technology, for a frequency modulation test, some functional tests are carried out with the help of a general-purpose electrical tester. The manual configuration workload is heavy and the degree of automation is low. Some test items cannot be carried out due to limited test instruments, and there is a lack of a complete set of new energy stations. Primary frequency modulation Test System Solutions
