Embodiment Construction

[0016] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] The invention is suitable for implementing and deploying the application of the WAMS application of the smart grid dispatching technical support system. The primary frequency regulation capability detection system of power system units is a sub-module of the WAMS application, based on the smart grid dispatching technology support system platform, to perform related event detection and assessment.

[0018] The primary frequency regulation capability detection system of power system units includes a primary frequency regulation event detection module, a unit running time statistics module and a visualized man-machine interface module. The relationship between the primary frequency regulation event detection module, the unit running time statistics module and the visualized man-machine interface module figure 1 As shown, the prim...

Abstract

The invention discloses a method for detecting primary frequency modulation capacity of power system units. The method includes: using WAMS (wide area measurement system) time sequence real-time library data to detect whether a primary frequency modulation event occurs or not; using the WAMS time sequence real-time library data to count unit operation time and design a visualized man-machine interface. By the method, the problem that a scheduling center cannot learn about the primary frequency modulation capacity of each unit in real time when power grid frequency is abnormal is solved. The fast and efficiency method is provided for power grid scheduling operators to detect the primary frequency modulation capacity, monitor the primary frequency modulation capacity of the units in real time, and increased the primary frequency modulation capacity of the units.

Description

technical field [0001] The invention belongs to the field of dynamic monitoring of power systems, and in particular relates to a detection system for the primary frequency modulation capability of power system units. Background technique [0002] With the increasing scale of power grid construction, there are more and more cases of abnormal frequency in the power system. The digital regulation system has been more and more widely used in my country's power system. While greatly improving the coordinated operation level of the machine network, the following problems have been found in actual operation: First, there are many types of generator set regulator manufacturers, and the performance is not good. First, there is a situation where the system performance is not up to standard; second, some power plants are not managed in a standardized manner, and the functions and parameters of the regulators have been changed, resulting in changes in the characteristics of the unit regu...
