New energy power generation system needs interface converter to connect to the grid. Because the type of new energy is different, its interface converter is also different. In order to adapt to the diversification of the modeling and control strategy of the converter, a generalized interface model is established in this paper. The model is based on the electromechanical transient simulation, which ignores the physics switching device and simplifies the control module. Finally, adaptive verifications are made in PSCAD/EMTDC and Matlab/Simulink for photovoltaic power generation system and wind power generation system. The results of simulation prove the validity of the generalized model.

Measurement And Control

A wireless measurement and control system for vegetable greenhouse is developed for the sake of overcoming the shortcoming of the wired measurement and control system such as complex wiring and low anti-interference capacity. In this environmental monitoring system, including the hardware design, software design and energy control strategy design, then we describe a comprehensive system testing process. In the hardware system testing, testing data verified the monitoring node performance. At last simulation data shows that the improved multi-hop network transmission protocol has obvious advantages.

Monitoring Application

A Monitoring system of ankle rehabilitation for paralyzed patients was successfully designed. The monitoring application on Android smartphone was made app inventor. This application uses bluetooth HC-05 as a data transmission between the ankle therapy aids and smartphone Android. A MPX5050DP sensor is used to determine the muscle condition of the paraplegic to measure the muscle strength scale and control the motor dc speed of ankle rehabilitation hardware. The virtual keys on the application are five instructions of therapeutic movement such as, dorsiflexion (200), plantarflection (450), eversion (100), inversion (100) and patterned of movement. The access time to operate the ankle rehabilitation hardware is 0.8 seconds. This application includes an alarm and a database that can be used as a monitoring system. An alarm menu serves as a reminder for patients to take therapy and database to store data readings of sensors that converted into scale and muscle pressure. A MPX55050DP sensor output is displayed on smartphone application, stored in database and the therapy results are reserved to document format. The capacity of the database corresponds to the memory on the smartphone. Based on the measurement results, the ankle therapy application on android smartphone can control the system movement of ankle therapy aids and as a monitoring system of therapy results for paralyzed patients and make easily in analyzing the condition of leg muscle strength.
