A virtual test method for intelligent IoT management of power grid security and stability control system

Abstract

The invention discloses a virtual test method for intelligent IoT management of a power grid security and stability control system. The method is firstly based on intelligent IoT technology, and connects the network of stability control devices in substations to a cloud server data platform; then uses virtual machine technology, based on The control strategy of the stability control device is actually operated on site, and the virtual machine of the stability control device is mirrored on the intelligent IoT platform; then the virtual stability control system and its intelligent IoT platform are established based on the virtual machine of the stability control device; The platform establishes a stability control system management and test master station to realize the full scene display of the stability control system and the management functions of the on-site stability control device; finally, the overall test of the stability control system and the individual test of the on-site stability control device are carried out through the virtual machine of the stability control device. The method of the invention can effectively, reliably, completely and efficiently test the huge and complex stability control system strategy in the power grid without withdrawing from the actual operating device of the power plant or substation.

Description

technical field [0001] The invention relates to the management, joint debugging and inspection of a power grid security and stability control system based on the intelligent Internet of Things, and in particular to a virtual test method for the management of the power grid security and stability control system intelligent IoT. Background technique [0002] With the rapid development of UHV AC and DC and new energy, the scale of the power grid system is getting larger and larger, and the requirements for the safety and stability control system (stability control system) of the power grid are getting higher and higher, and the scale of the power grid safety and stability control system continues to increase. The level of complexity continues to grow. At the same time, based on the development of cloud computer technology and the construction of the intelligent Internet of Things, how to use the latest technical means to improve the intelligence level of the stability control s...

Problems solved by technology

The collection of data information is incomplete, which can only meet the basic management needs, and cannot carry out real-time management of the stability control device and the stability control system

[0004] At present, the joint commissioning, inspection and testing of the power grid stability control system is still mainly based on manual incremental testing. The test method is single-point and point-to-point testing. The test efficiency is low, and it is difficult to cooperate with the test strategy, and it is difficult to verify all aspects of the strategy.

Part of the remote test mainly adopts the manual arrangement of test devices in the substation, and uses the test device to apply external voltage, current and interactive information to the stability control device. Based on the fault sequence, the device inspection test is carried out in a sequential manner, which loses the original system dynamics. characteristics, the test results are difficult to reflect the real situation of the system
