In MicroGrid if traditional synchronous generators were used as the main power support, the frequency of MicroGrid would fluctuate greatly during MicroGrid operated from isolated mode to grid-connected mode, and some distributed generations maybe were disconnected from the grid by low frequency relay.

如果选择微型燃气轮机作为微网的主要功率支撑手段，在微网从并网向孤网过渡过程中，系统频率波动较大，且部分分布式电源有可能在低频保护动作下与电网隔离，不利于微网的稳定运行；增加储能设备后，储能设备对于微网的稳定运行可发挥重要的作用。

Pointing to some problems such as easy defect of joint, big pushing to voltage of power net and frequent defects existed in hydraulic station control system of BF, the reforming included replacing pressure meter with electric joint by pressure transmitter with intellectual digital display, replacing alternating contactor by alternating frequency conversion technique and increasing relay control to 984PLC control has been done in Jigang.

针对高炉液压站控制系统存在的接点易损坏、对电网电压冲击大、故障频繁等问题，改造采用带智能数显表的压力变送器代替电接点压力表，应用交流变频技术代替交流接触器，并将继电器控制升级为984PLC控制。

You're never going to build the same smart grid twice, so you have to look for overriding themes, says Brad Gammons of IBM, a computer giant, which has helped dozens of utilities with their smart-grid implementations.

你将不会建两个一样的智能电网，所以你得注意最重要的主题，计算机巨头IBM公司的Brad Gammons这样说道。

"You're never going to build the same smart grid twice, so you have to look for overriding themes," says Brad Gammons of IBM, a computer giant, which has helped dozens of utilities with their smart-grid implementations.

有些电力公司也许希冀用技术将用电效率最大化。&你将不会建两个一样的智能电网，所以你得注意最重要的主题，&计算机巨头IBM公司的Brad Gammons这样说道。

In the incineration plant, garbage incineration, when the heat generated by the recovery will be converted into energy, the supply of electricity required for the incineration plant, the remaining can be supplied to the new energy grid.

在焚化厂里，垃圾焚化时所产生的热会被回收转换成能源，供应焚化厂所需的电力，剩余的还可供应给新能源电网。

This paper has introduced that structure of inductance ballast of the gas discharge lamp and structure and performance of electronic ballast, has given some examples for applying the electronic ballast and has compared parameter change and light efficiency of inductance ballast with which of electronic ballast when voltage of electric power net changes.
