Standards Development
The scope of this technical specification is to define the requirements for hardware -in-the-loop simulation test of power system stability control system, therefore it relates to general requirements, test objects and scope, test procedure, test contents, and test quality management.
This technical specification provides guidance for the modeling, testing, and management of test quality of power system stability control system, so that the performance of the power system stability control system can be verified and the potential deficiency can be figured out.
AC/DC hybrid power grids are increasing rapidly with the vigorous development of long -distance, high- capacity HVDC transmission technology. With the dramatic changes in the form and operation characteristics of the bulk power system, the power system stabi lity control system become increasingly complex. Because of the wide variety of models, large scale of equipment, and various technologies, it is difficult to verify the strategy of the power system stability control system and to study the impact on the s tability characteristics of the bulk power system. Existing test methods fail to thoroughly test the power system stability control system. The method to solve this problem is to establish a hardware -in-the-loop simulation platform of the power system stability control system. The hardware-in-the-loop simulation platform is able to provide a near- real system operation environment and the capability to integrate other real important devices, such as the control and protection device of HVDC, into the real-time simulation. Thus, the accuracy and performance specification of power system stability control system can be fully tested. Due to the advanced performance of hardware-in-the-loop simulation, plenty of countries have already utilized hardware -in-the-loop simulation test for power system stability control system, such as China, United States, Canada, France, Turkey, Belgian, Brazil, Chile, Malaysia, etc. Especially in China, hardware -in-the-loop simulation test has been standardized before the on-site commissioning of the power system stability control system. Due to the comprehensive test, power system stability control systems effectively maintain the safe and stable operation of Chinese power grid and there is no major blackout occurred in the last decade.
By formulating this standard, it is able to further strengthen and standardize the hardware -in-the-loop simulation test of the power system stability control system. Especially, the comprehensive test of the newly connected model of the stability contr ol device should be fully compliant with the design requirements of the control strategy function, setting value, and action characteristics, so as to improve the reliability and safety of the power system stability control system, and ensure the safe and stable operation of the power system. This standard is proposed in order to clarify the technical requirements for hardware -in-the-loop simulation test of the power system stability control system.
