The design of voltage measuring system of TCR

TCR is one type of reactive power compensation equipment which is popular used in power system nowadays. Its precision of compensation affects the quality of electrical energy. As the data source, the data acquisition section's performance will impact the function of control system directly, so as to affect the compensation effect. The paper designs a suit of voltage measuring system applied in reactive power compensator TCR, which is based on the chip CS5460A, together with the 51 SCM. The paper particularly dissertates the hardware design structure of system and the software program, also presents the flow chart. Practice indicates that the system has the superiorities of simple circuit, high precision, good real-time character, low cost and so on, which implies that the system has high practical value.
