Thái độ của con người sau khi thay đổi cuộc sống thường là như "thế". Chỉ có một số rất ít nhớ lại tình trạng trước đây của mình là như thế nào, và ai là người luôn ở bên cạnh mình trong những lúc đau khổ nhất ...

The document discusses several philosophical ideas and quotes from Thich Nhat Hanh on living life to its fullest. Some of the key ideas expressed are to live freely without attachments, to find happiness from within oneself rather than seeking it externally, and to continually improve oneself each day through learning. Living with compassion and generosity of spirit is emphasized.
Pd 1995 10-2-the upfc a new approach to power transmission controlSudeepthg Sudeepth
The document describes a new approach to power transmission control called the Unified Power Flow Controller (UPFC). The UPFC consists of two voltage-sourced inverters connected to a common DC link that allow real and reactive power to flow in either direction. It can independently control both the real and reactive power flows at the sending and receiving ends of a transmission line. This provides capabilities beyond existing approaches like thyristor-controlled series capacitors and phase angle regulators. Simulation results demonstrate the UPFC's performance under different system conditions.

The document describes a new type of Flexible AC Transmission System (FACTS) device called the Distributed Power Flow Controller (DPFC).
The DPFC is derived from the Unified Power Flow Controller (UPFC) by eliminating the common DC link between the shunt and series converters. Instead, active power is exchanged between the converters through the transmission line at the third harmonic frequency.
The DPFC employs distributed FACTS concepts using multiple single-phase series converters instead of a single three-phase series converter like in the UPFC. This provides redundancy to increase reliability. It also avoids the need for high voltage isolation between phases since the converters are single-phase and floating.

The document describes a new type of Flexible AC Transmission System (FACTS) device called the Distributed Power Flow Controller (DPFC). The DPFC is derived from the Unified Power Flow Controller (UPFC) by eliminating the common DC link between converters and distributing multiple single-phase series converters along the transmission line. This allows active power exchange between converters through the line using third harmonic frequencies instead of a DC link. The DPFC has the same control capabilities as the UPFC but offers improved reliability due to redundancy of series converters and lower cost due to smaller, isolated converters without high voltage insulation requirements. Experimental results from a scaled DPFC prototype are also presented.

Hơn 10 năm trước, trong tâm trạng của một sinh viên mới ra trường đầy mơ mộng, anh chọn cho mình nickname là “bautroixanh21” – cái tên đầy cảm xúc của dân “Khối C”. Tôi soạn tập truyện và thơ này để dành tặng cho anh, mong anh bình an ở một phương trời mới, cuộc sống mới.
