This paper presents the characteristics of the thyristor controlled series compensation by adjustable coupling , deduces the adjustable reactance formula considering leakage reactance, and presents a fast and effective power regulation algorithm with offline regulation according to the characteristics of the step regulation of reactance by adjustable coupling. In transient stability control process,...
Stand- alone photovoltaic systems have solved power supply in the many remote areas. Inverter is the key component of photovoltaic system. By paralleling several mid/low-power inverter units to compose a large power supply system, both the capability and the reliability of power supply system can be enhanced. The circumfluence among parallel inverter in PV is the key reason for preventing the parallel...
In order to share the load and restrain circumfluence, it is described that a digital current sharing control technique for modularized UPS parallel operation in detail in this paper, and the structure of parallel system is presented. Based on the analysis of circumfluence of paralleled system, characteristic of the power regulation, a novel digital power detection technique is deduced. With measuring...
