Embodiment 1

[0035] Such as figure 1 As shown, a method for debugging parameters of a new energy control system includes: for a control system being debugged, exporting a parameter text file containing only main parameters from the control system;

[0036] Use the file comparison tool to compare the parameter text file with the template parameter file to determine whether the main parameters are different; if there is a difference and it is a configuration error, modify the difference parameter in the parameter text file to the corresponding parameter in the template parameter file Consistent, get the modified parameter text file;

[0037] Import the modified parameter text file into the relational database or system configuration file of the control system during debugging, and align the main parameters in the control system with the corresponding parameters in the modified parameter text file;

[0038] Start the new energy control system and verify whether the main parameters of the con...

Embodiment 2

[0053] Such as Figure 4 As shown, a new energy control system parameter debugging system includes:

[0054] An export module, for the control system being debugged, derives a parameter text file containing only main parameters from the control system;

[0055] Compare and modify the module, compare the parameter text file with the template parameter file through the file comparison tool, and judge whether there is a difference in the main parameters; if there is a difference and it is a configuration error, modify the difference parameter in the parameter text file to be the same as the template parameter file The corresponding parameters in are consistent, and the modified parameter text file is obtained;

[0056] The import module imports the modified parameter text file into the relational database or system configuration file of the control system during debugging, and aligns the main parameters in the control system with the corresponding parameters in the modified para...

Embodiment 3

[0061] A new energy control system parameter standardization visualization method, figure 2 It is a relational diagram of the parameter file of the new energy control system in the embodiment; for the power control system agc and avc of the 100MW photovoltaic power station, it specifically includes the following steps:

[0062] 1. For the power control system being debugged, export the configuration parameters to a parameter text file. In the specific example, a commercial database and configuration files are used to save parameters, and a large amount of platform-level configuration information such as graphics system and communication system is stored in a commercial database. Management tools are time-consuming and labor-intensive. The main parameters related to the control system are as follows:

[0063] The global parameters are as follows:

[0064]

[0065] There are 200 centralized inverters in the station, and the inverter parameters are as follows:

Abstract

The invention discloses a new energy control system parameter debugging method and system, and the method comprises the steps: for a control system in debugging, exporting a parameter text file whichonly comprises main parameters from the control system; comparing the parameter text file with a template parameter file through a file comparison tool, and judging whether main parameters are different or not; modifying difference parameters in the parameter text file to be consistent with corresponding parameters in the template parameter file in response to the difference and the configurationerror; importing the parameter text file after comparison and modification into a relational database or a system configuration file of the control system in debugging, and performing data alignment on the main parameters in the control system and corresponding parameters in the parameter text file after comparison and modification; and starting the new energy control system to verify whether themain parameters of the control system pass debugging through experiments. After debugging is completed, the parameter text file is saved and archived to serve as a template, and the template is published while the control system is published.

Description

technical field [0001] The invention belongs to the technical field of new energy automatic control systems, and in particular relates to a parameter debugging method and system of a new energy control system. Background technique [0002] New energy technologies such as photovoltaic power generation, wind power generation and energy storage have been rapidly developed and applied in my country, and will become an important part of my country's power system in the future. In new energy fields such as photovoltaic power generation, wind power generation, and energy storage, in order to meet safe production and operation, grid-connected technical conditions require grid-connected photovoltaic power generation, wind power generation, and energy storage systems to have active power control and reactive power voltage control functions. The control objects have the characteristics of wide distribution and large number, which leads to the situation of many parameters and complex co...
