- Abstract:
- The drainage system is an intricate huge system with strong coupling, great time delay, nonlinearity and uncertain characteristics. In order to realize the real-time control of the system, it is optimally controlled online and the process parameters are adjusted, which can easily lead to long commissioning cycle and high safety risk. To guarantee the rationality and accuracy of real-time control logic, the first principal model is used to test the control logic of the system before delivery, and provide an important mathematical experiment environment for the optimal control of drainage system. Through the function module of Simuwater, an urban water system control simulation model, in combination with the widely used OVATION control system and the drainage system simulation software SWMM, the simulation and testing of the drainage system control logic in the real production environment under the mathematical model environment is realized. The simulated environment was used to carry out a case study of Changzhou Wangjiatang-Huijiatang drainage system, set up the SWMM model of the case area, develop the closed-loop control logic of multistage pumping station optimized dispatching in OVATION virtual controller, and replace the conventional regular control of mechanism model with the closed-loop control logic of standard control system. The advanced control algorithm is used to simulate the whole process of multi-condition. Through the coupling simulation of the real control system and the mechanism model, the system performance of the case is significantly improved, which can provide a reference for the model-based control logic simulation of the drainage system, and provide a realistic basis for the real automatic control of the drainage system.
