Pumped-storage unit control program dynamic simulation test system and method for full working conditions

Abstract

The invention discloses a pumped storage unit control program all condition dynamic simulation test system and method. The system comprises PLC programming terminal equipment, a PLC CPU module, and a field display control terminal mutually connected through a network. The method comprises the steps that a control program module to be tested and equipment response simulation program module are loaded in each CPU module; in testing, the control program module to be tested emits an equipment operation command to the equipment response simulation program module, the equipment response simulation program module generates a field equipment state simulation signal through simulation calculation and feeds the signal to the control program module to be tested, the control program module to be tested continue to execute a subsequent flow and equipment control according to the feedback signal, and in the testing process, the state monitoring is carried out always. According to the system and the method, additional special simulation equipment is not needed, only the existing hardware and software resources of a monitoring system to be tested are used, the system and the method are suitable for the simulation test of a multi-field multi-unit collaborative work program and have high promotion and application values.

Description

technical field [0001] The invention relates to the technical field of control of a pumped storage unit, in particular to a dynamic simulation test system and method for a control program of a pumped storage unit under full working conditions. Background technique [0002] The control program of the pumped storage unit is the control core of the whole unit, and the correctness, safety and reliability of the control program must be ensured when the unit is started up and running. Therefore, after the development and writing of the unit control program is completed, it is necessary to simulate the conditions of the field equipment and conduct a dynamic operation test of the control program to verify whether the relevant control functions meet the production process and design requirements. [0003] At present, the testing of control programs for hydroelectric units usually requires the development of simulation equipment specially used for program testing. During the program ...

Problems solved by technology

Therefore, for pumping-related control programs that require cooperation between units or between units and public equipment, this point-to-point program simulation test method is difficult to complete dynamic simulation testing and functional verification.

In addition, developing a set of special equipment for program dynamic testing and simulation with relatively complete functions is also a very complicated and arduous task, requiring a lot of manpower, material and financial resources

[0004] Usually, the commissioning of the pumping-related control programs between units or units and public equipment is carried out on-site after the specific units and public equipment are installed and built. This will not only delay the on-site commissioning time, but also once a test error occurs, It is also likely to cause damage to field equipment
